fix linking with mold on 32bit archs; rel 6

for some reason gcc assumes all linkers should search for libraries in
/lib and /usr/lib and deliberately skips them when constructing linker
command line. this assumption does not apply to mold though and does not
seem reasonable in general hence drop this logic and pass unfiltered
LIBRARY_PATH to linker
