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'.
|
|
|
|
In addition, status should be initialized to 0 and not -1.
