Subject: external-toolchain: handle libstdc++/libgcc_s for BR toolchains
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2bf32a3307b8d184396a02056b454ec98beeda4c;p=buildroot.git

external-toolchain: handle libstdc++/libgcc_s for BR toolchains

Most toolchains have their libraries either in /lib or /usr/lib
relative to their ARCH_SYSROOT_DIR. Buildroot toolchains, however,
have basic libraries in /lib, and libstdc++/libgcc_s in
/usr/<target-name>/lib(64).
