[PATCH, libgomp, libatomic] Fix configure for systems without libpthread

[Pavel Chupin]

On Android pthread is integrated into libc.
Attached patch fixes configures for this case by trying to build test
without -pthread -lpthread.

2013-04-01  Pavel Chupin  <pavel.v.chupin@intel.com>

        Fix libatomic and libgomp configure for systems without libpthread
        * libatomic/configure.ac: Add test without -pthread -lpthread.
        * libgomp/configure.ac: Ditto.
        * libatomic/configure: Regenerate.
        * libgomp/configure: Regenerate.

OK for trunk?
