Subject: toolchain-external: Commonize /lib/<tuple> symlinks for Linaro toolchains
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ffafb77da2d298cb5f4b0ea8486c7596f51af18e;p=buildroot.git

toolchain-external: Commonize /lib/<tuple> symlinks for Linaro toolchains

As proposed initialy by Matthew Fornero [1], commonize the creation of
symlinks from {/usr}/lib to {/usr}/lib/<tuple> for Linaro toolchains.

This symlinks are only required for old Linaro toolchains.
