[PATCH 0/13] Add musl support to GCC

2015-05-08  Szabolcs Nagy  <szabolcs.nagy@arm.com>

	* config/glibc-stdint.h (OPTION_MUSL): Define.
	(INT_FAST16_TYPE, INT_FAST32_TYPE, UINT_FAST16_TYPE, UINT_FAST32_TYPE):
	Change the definition based on OPTION_MUSL for 64 bit targets.
	* config/linux.h (OPTION_MUSL): Redefine.
	* config/alpha/linux.h (OPTION_MUSL): Redefine.
	* config/rs6000/linux.h (OPTION_MUSL): Redefine.
	* config/rs6000/linux64.h (OPTION_MUSL): Redefine.
