[OpenEmbedded] Fix lib paths for OpenEmbedded targets
Summary:
The lib paths are not correctly picked up for OpenEmbedded sysroots (like arm-oe-linux-gnueabi) for 2 reasons:
1. OpenEmbedded sysroots are of the form <sysroot>/usr/lib/<triple>/x.y.z. This form is handled in clang but only for Freescale vendor.
2. 64-bit OpenEmbedded sysroots may not have a /usr/lib dir. So they cannot find /usr/lib64 as it is referenced as /usr/lib/../lib64 in clang.
This is a follow-up to the llvm patch: D48861
