-	* config/linux.h (OPTION_MUSL): Define.
-	(MUSL_DYNAMIC_LINKER, MUSL_DYNAMIC_LINKER32,)
-	(MUSL_DYNAMIC_LINKER64, MUSL_DYNAMIC_LINKERX32,)
-	(INCLUDE_DEFAULTS_MUSL_GPP, INCLUDE_DEFAULTS_MUSL_LOCAL,)
-	(INCLUDE_DEFAULTS_MUSL_PREFIX, INCLUDE_DEFAULTS_MUSL_CROSS,)
-	(INCLUDE_DEFAULTS_MUSL_TOOL, INCLUDE_DEFAULTS_MUSL_NATIVE): Define.
-	* config/linux.opt (mmusl): New option.
-	* doc/invoke.texi (GNU/Linux Options): Document -mmusl.
-	* configure.ac (gcc_cv_libc_provides_ssp): Add *-*-musl*.
-	(gcc_cv_target_dl_iterate_phdr): Add *-linux-musl*.
-	* configure: Regenerate.
