+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.
+
+Adapted to glibc-2.39.
