# having to do the install for each test.

# require additional programs including /bin/sh, /bin/true, and
# /bin/echo, all of which we build below to limit library dependencies
# to just those things in glibc and language support libraries which
# we also copy into the into the rootfs. To determine what language
# support libraries we need we build a "test" program in either C or
