PRU does not export __end symbol because it is ambiguous for it.
Users are expected to use instead the section markers __text_end,
__data_end, __bss_end or __noinit_end.

	libraries are supported for PRU.
	(check_gc_sections_available): Mark PRU as not supported.
	* testsuite/ld-elf/eh-frame-hdr.d: Disable for PRU.

	* testsuite/ld-elf/group8a.d: Likewise.
	* testsuite/ld-elf/group8b.d: Likewise.

	* testsuite/ld-elf/pr14926.d: Likewise.
	* testsuite/ld-elf/sec-to-seg.exp: Likewise.
	* testsuite/ld-elf/sec64k.exp: Mark sec64k case as too big for PRU.
	* testsuite/ld-srec/srec.exp (run_srec_test): Add setup for PRU.
