PR 52390 complains that the libgcc morestack support tests for __glibc__
for code that can only happen on GNU/Linux systems. This patch adds a
test for __linux__ as well. This will presumably improve matters when
using glibc on a non-Linux system. Bootstrapped and ran Go testsuite on
x86_64-unknown-linux-gnu. Committed to mainline.
