Fix for #144495 by 6f4add3 broke sanitizer-aarch64-linux buildbot.
compiler-rt/lib/fuzzer/tests build failed because the linker was
looking gcc_s without '-l' appended.
The CMake script was adding the library name without the required
'-l' prefix. This patch adds the -l prefix changing gcc_s to -lgcc_s
and gcc to -lgcc.
