flag.

the run-time `NIXPKGS' environment variable.

configure flag.
* README: Mark Nixpkgs as optional.
* distro/packages/databases.scm, distro/packages/guile.scm,
distro/packages/typesetting.scm: Change uses of `nixpkgs-derivation*'
to `nixpkgs-derivation', to avoid failing at compile-time.
* guix/ui.scm: New file.
* Makefile.am (MODULES): Add it.
* po/POTFILES.in: Add it.
* guix-build.in: Use it.
(_, N_, leave): Remove.

(_, N_, leave): Remove.
* guix/store.scm (add-indirect-root): New operation.
* guix-build.in (show-help): Document `--root'.
(%options): Add `--root'.
(guix-build)[register-root]: New procedure. Call it when `--root' is
passed.
* release.nix (distro.hello)[buildPhase]: Tee the log to $out. Add a
`name' attribute; remove `buildInputs' and instead use the full path
to `guix-build'.
* tests/builders.scm (%bootstrap-inputs): Use %BOOT0-INPUTS from the distro.
* tests/packages.scm (%bootstrap-inputs): Likewise.
* tests/derivations.scm (%coreutils): Alias for %BOOTSTRAP-COREUTILS&CO.
* distro.scm (not-colon): New variable.
(%patch-directory): Rename to...
(%patch-path): ... this. Turn into a list. Expect $DISTRO_PATCH_PATH
to be a colon-separated search path.
(%bootstrap-binaries-directory): Rename to...
(%bootstrap-binaries-path): ... this. Likewise.
(search-patch, search-bootstrap-binary): Adjust accordingly.
* pre-inst-env.in: Change to use `DISTRO_PATCH_PATH' and
`DISTRO_BOOTSTRAP_PATH'.
* Makefile.am (.scm.go): Use `pre-inst-env' instead of re-defining the
environment variables, except for `DISTRO_INSTALLED_PATCH_DIRECTORY'
and `DISTRO_INSTALLED_BOOTSTRAP_DIRECTORY'.
* distro/packages/base.scm (gcc-4.7)[arguments]: In the `pre-configure'
phase, patch all the relevant gcc/config files, not just those for
x86_64-linux-gnu.
* guix/build/utils.scm (substitute*): Remove special syntax for
list-of-files; instead, check whether FILE is `list?' at run time.
* distro/packages/base.scm (gcc-4.7, %binutils-static): Adjust
accordingly.
* guix/packages.scm (package-source-derivation): Add `system'
parameter. Pass it to METHOD.
(package-derivation)[expand-input]: Pass SYSTEM to
`package-derivation' and `package-source-derivation'.
* distro/packages/base.scm (package-with-bootstrap-guile)[boot]: Pass
SYSTEM to FETCH.
* guix/derivations.scm (imported-files): Call
`build-expression->derivation' with SYSTEM, not (%current-system).
(build-expression->derivation): Pass SYSTEM to `imported-modules' and
`compiled-modules'.
* guix/derivations.scm (%guile-for-build): Initialize to #f.
(imported-files, imported-modules, compiled-modules): Add `guile'
keyword parameter. Pass it down to `build-expression->derivation'.
(build-expression->derivation)[guile-drv]: New variable. Pass it as
the #:guile parameter for `imported-modules' and `compiled-modules'.
* tests/derivations.scm: Set %GUILE-FOR-BUILD to the derivation of
%BOOTSTRAP-GUILE.
* distro/packages/base.scm (%glibc-stripped): Copy all of Linux-Libre's
`include/asm' directory; copy a few linux/ headers too.
(%bootstrap-glibc): Update tarball hash.
* distro/packages/base.scm (%static-inputs): Add an `awk' -> `gawk', and
`sh' -> `bash' symlinks. Add `fgrep' and `egrep'.
(%bootstrap-coreutils&co): Use new tarball that contains that
symlink.
* distro/packages/bootstrap/x86_64-linux/bash,
distro/packages/bootstrap/x86_64-linux/mkdir,
distro/packages/bootstrap/x86_64-linux/tar,
distro/packages/bootstrap/x86_64-linux/xz: Use binaries from that
tarball (the previous binaries hadn't gone through
`remove-store-references', which is fixed now.)
* guix/derivations.scm (imported-files)[parent-dirs]: Move to...
(parent-directories): ... here. New procedure.
(compiled-modules): New procedure.
(build-expression->derivation): Use it.
* tests/derivations.scm ("build-expression->derivation with modules"):
New test.
