Subject: [PATCH] clang: driver: Add dyld-prefix when checking sysroot for ldso
path
* the dyld-prefix shall be taken into account when the default
path for the dynamic linker has to be checked.
* this patch shall be used as annex to the next patch:
'clang: driver: Check sysroot for ldso path' which includes
the usrmerge scenario.
