gnu-phdrs.test uses 2 precompiled objects and has issues:

- It does not test all possible program headers.
- It does not test target-specific headers (arm, mips).
- It does not use --strict-whitespace --match-full-line to check the format of the output.
- It is possible to check things better/nicer.

This patch makes gnu-phdrs.test to stop using binaries and addresses issues above.

I am going to use it as a base for a follow-up patch that should also test
all section to segment mapping conditions that we currently have
