Fix CFLAGS override in sysdeps/ieee754/dbl-64 Use += instead of = to avoid overriding target specific CFLAGS settings. Ideally the settings in target Makefiles would have precedence, but the Makefile inclusion order does not allow that, with this fix at least the target settings are not dropped. 2017-08-24 14:56:11 +00:00			`CFLAGS-branred.c += $(config-cflags-nofma)`
