It appeared in commit21cdc2e77a("fix 32-bit link with gcc") that linker options must be prefixed by -Wl, when using CC. So CPU_LDFLAGS is prefixed in rte.lib.mk. Then commit815cfb7925("fix link of combined shared library using CC") introduced another prefixing of CPU_LDFLAGS in rte.sharelib.mk, included in lib/Makefile. Because CPU_LDFLAGS is an exported variable, the prefixing is done twice. Initial patch of commit815cfb7925had a workaround but it hasn't been applied in favor of this proper fix. Now variables are not overriden when prefixing. Signed-off-by: Thomas Monjalon <thomas.monjalon@6wind.com>
