The patch-specs.sh utility dumps the GCC specs of a given toolchain and modifies them to always include $STAGING_DIR in the link and compiler command lines, this makes most -I and -L flags unnecessary and lets the compiler automatically find libraries and headers in the staging dir, also solves the majority of -rpath issues. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@29767 3c298f89-4303-0410-b956-a3cf2f4a3e73
