distro: make-bootstrap: Have libc's functions search for `sh' in $PATH. 

* distro/packages/make-bootstrap.scm (%glibc-with-relocatable-system,
  %standard-inputs-with-relocatable-glibc): New variables.
  (%static-inputs)[gawk]: Apply `gawk-shell.patch'.
  [finalize]: New procedure.
  Build all the packages against %STANDARD-INPUTS-WITH-RELOCATABLE-GLIBC.
  (%glibc-stripped): Inherit from %GLIBC-WITH-RELOCATABLE-SYSTEM.
  (%gcc-static, %guile-static): Build against
  %STANDARD-INPUTS-WITH-RELOCATABLE-GLIBC.
* distro/packages/patches/gawk-shell.patch,
  distro/packages/patches/glibc-bootstrap-system.patch: New files.
* Makefile.am (dist_patch_DATA): Add them.

As for libc's `system', change Awk to look for `sh' in $PATH. This patch is
only meant to be used during bootstrapping, where we don't know in advance the
absolute file name of `sh'.

We want to allow builds in chroots that lack /bin/sh. Thus, system(3)
and popen(3) need to be tweaked to use the right shell. For the bootstrap
glibc, we just use whatever `sh' can be found in $PATH. The final glibc
instead uses the hard-coded absolute file name of `bash'.
