[patch] libgomp test fixes for FreeBSD

[Andreas Tobler]

Hello,

the below patch fixes three unresolved and a FAIL test case in libgomp.
The FAIL test case can be solved with removing the include of the
alloca.h header which is not present on FreeBSD.

On Linux this header will be pulled in via stdlib.h if we define
_GNU_SOURCE. And this we do.

Tested on Linux/x86_64 and FreeBSD11.0 amd64.
On FreeBSD we get all test cases pass. (on Linux too, no regression)

Ok for trunk?

Thanks,
Andreas
