Subject: build: Pass -iremap gcc option as a single argument
X-Git-Tag: v17.01.5~290
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=94f079e338d69f885645d2c99f235626b0ad2137;p=openwrt%2Fopenwrt.git

build: Pass -iremap gcc option as a single argument

Passing -iremap argument separately causes problems with projects that
use scons and its ParseFlags function. Consider this SConscript
example:

    env = Environment()
    d = env.ParseFlags("-iremap one:two")

ParseFlags will interpret one:two as a file name and the returned dict
d will contain only "-iremap". When the -iremap is passed to the
compiler without an argument, compilation obviously fails.
