From: Peter Korsgaard Date: Mon, 2 May 2011 21:58:20 +0000 (+0200) Subject: Get rid of unneeded CFLAGS X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=125e2558b2ec253d255bf3a1fb2950efc358c8d2;p=buildroot.git Get rid of unneeded CFLAGS Now that we use a wrapper for external toolchains (and internal ones default to the correct setting), we no longer need to explicitly pass sysroot/march/mtune/mabi/floating point mode in TARGET_CFLAGS.
