Subject: CC: uclibc++: make g++-uc* wrappers relocatable
X-Git-Url: http://git.openwrt.org/?a=commitdiff_plain;h=962e737dab91c929fb5f9c8f77db6923150c7812;p=openwrt%2Fsvn-archive%2Fopenwrt.git

CC: uclibc++: make g++-uc* wrappers relocatable

The g++-uc wrapper hardcodes $(STAGING_DIR) and $(TOOLCHAIN_DIR) paths which
will not work outside of the original build environment.

Replace the hardcoded staging_dir occurences with paths relative to the
$STAGING_DIR environment variable to make the g++-uc* wrappers usable in an
SDK environment.

Fixes the libdb47 build failure reported at
  https://lists.openwrt.org/pipermail/openwrt-devel/2015-April/032455.html
