Subject: [PATCH 4/8] clang: Prepend trailing '/' to sysroot
This is needed to handle a case where clang
isntall and target sysroot are perilously same
e.g.
sysroot = /mnt/clang/recipe-sysroot
clang install = /mnt/clang/recipe-sysroot-native
in this case it will mistakenly assume that
clang is installed under the same sysroot dir
and it will try to add relative ../lib paths
to linker steps which would then be wrong
since they will become relative to clang
installation and not sysroot
