Patch for hppa1.1-unknown-rtems

["Kaveh R. Ghazi" <ghazi at caip dot rutgers dot edu>]

Currently, hppa1.1-unknown-rtems will not work because config.gcc sets
up Makefile to request pa/pa-pro.h which does not exist.

I noticed that there are two hppa1.1-unknown-rtems clauses in
config.gcc.  The second one appears to allow cc1 to build.

So here's a patch to remove the bogus one, plus a minor warning fix
for a redefinition blather in every file.

Tested via a cross compile of cc1 from solaris2.7 to
hppa1.1-unknown-rtems.

Okay to install?

		Thanks,

	* pa/elf.h (ASM_DECLARE_FUNCTION_NAME,
	ASM_OUTPUT_EXTERNAL_LIBCALL): Undef before defining.
	* config.gcc (hppa1.1-*-rtems*): Remove duplicate clause.
