The testcase gcc.dg/cpp/assert4.c, which tests that #system(linux) is true
if and only if __gnu_linux__ is defined, wasn't updated for the changes
associated with Android support that arranged for __linux__ to be defined
for all systems with the Linux kernel but __gnu_linux__ only to be defined
for systems using some form of glibc (not counting uClibc) with that
kernel. I've applied this patch to make the test test __linux__ instead
of __gnu_linux__. Tested x86_64-unknown-linux-gnu.
