| 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'.
