cobol, driver: Remove platform-specific options [PR119414].

As discussed in the PR, the options had been added during development
to handle specific cases, they are no longer needed (and if they should
become necessary, we will need to guard them such that individual
platforms get the correct handling).

	PR cobol/119414

gcc/cobol/ChangeLog:

	* gcobolspec.cc (append_rdynamic,
	append_allow_multiple_definition, append_fpic): Remove.
	(lang_specific_driver): Remove platform-specific command
	line option handling.
