[gentoo-dev] [PATCH] profiles: workaround sandbox bug with getcwd() configure test (gl_cv_func_getcwd_path_max)

[Sam James <sam@gentoo.org>]

Workaround for sandbox bug which causes this gnulib configure test to take
many real hours on slower machines, and certainly a huge amount of CPU hours
on others.

Spoof the same result as configure gets on a modern glibc & musl system for now.

Closes: https://bugs.gentoo.org/922652
