tests: robustify run-strip-nothing.sh against unstripped libc_nonshared.a

When glibc's libc_nonshared.a contains objects with debug info,
this debug info is leaked into every output file produced by gcc.
Change run-strip-nothing.sh to use "gcc -s" instead of plain "gcc"
for producing objects without debug info.
