Subject: build: don't add -fno-plt for ARC
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=be9e991b8806841a1c209ed7e2864d48da0de1b5;p=openwrt%2Fsvn-archive%2Fopenwrt.git

build: don't add -fno-plt for ARC

Curent ARC toolchain fails to build libstdc++ if -fno-plt is used.
Lots of following error messages appear:
------------------->8------------------
...
staging_dir/toolchain-arc_arc700_gcc-arc-2015.06_uClibc-1.0.9/arc-openwrt-linux-uclibc/bin/ld:
BFD (GNU Binutils) 2.23.2 assertion fail elf32-arc.c:2786
collect2: error: ld returned 1 exit status
------------------->8------------------

In newer binutils (still in development) for ARC rewritten from
scratch this seem to not happen, so once new binutils for ARC hit
the street this patch might be reverted.
