Eric Le Bihan 32fe6a540b skalibs: make ld use dummy file when configuring
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, instead of /dev/null, when
trying to detect some libraries at configuration time.

Fixes http://autobuild.buildroot.net/results/288/288fc31cd10ffe3cd93371c7be37d79452a91768/

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.
