Subject: [PATCH] Make linker use dummy file when testing libs

For some architectures, like Xtensa or HPPA, ld from binutils requires
the output file to be a regular file, as mentioned in a bug report on
the mailing list [1].

So, use a dummy file as output file for ld in trylibs(), instead of
/dev/null.
