Subject: rules.mk: Create TARGET_ASFLAGS; force -mno-mips16
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5b3445c60bb23b7414119482fb784f68fbcc82db;p=openwrt%2Fstaging%2Fjow.git

rules.mk: Create TARGET_ASFLAGS; force -mno-mips16

Create and use a TARGET_ASFLAGS, defaulting to TARGET_CFLAGS.

MIPS .S files reasonably assume they are not in mips16 mode. Because
"-mips16 -mno-mips16" results in -mno-mips16, I can append that to the
TARGET_ASFLAGS. This should be done with $(filter-out)?
