	__float128 restrictions.

[libgcc]

	PR target/70381
	* configure.ac (powerpc*-*-linux*): Rework tests to build
	__float128 emulation routines to not depend on using #pragma GCC
	target to enable -mfloat128.
	* configure: Regnerate.

[gcc/testsuite]
2016-04-11  Michael Meissner  <meissner@linux.vnet.ibm.com>

	PR target/70381
	* gcc.target/powerpc/float128-1.c: New tests to make sure the
	__float128 emulator is built and runs.
	* gcc.target/powerpc/float128-1.c: Likewise.
