Compiled clang doesn't have search paths properly set up

As can be seen below, newly compiled clang can't figure out paths for crtbegin.o and crtend.o. -lgcc also fails, but succeeds if -L is explicitly passed to the linker. After linking
succeeds (with a manual invocation), the produced binary then seems to expect /lib64/ld-linux-x86-64.so.2 to exist. The latter can probably be fixed by tweaking the -dynamic-linker flag.
