gnu/packages/patches/glibc-bootstrap-system.patch

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