Subject: UCW::Configure::C: de-reference CPU_ARCH in COPT
X-Git-Tag: v5.0~140
X-Git-Url: http://mj.ucw.cz/gitweb/?a=commitdiff_plain;h=f0c77ee3ca96b8ce3312dfcdc0a450644b09fce6;p=libucw.git

UCW::Configure::C: de-reference CPU_ARCH in COPT

Originally, when CONFIG_EXACT_CPU was enabled, COPT contained `-march=$(CPU_ARCH)',
which worked when it was used in a Makefile, but not when doing a test
compile in the configure script.

I changed it to dereference the variable immediately.
