With -N, the test still fails, but because it has "RWE" where "R E" is 
expected.

regexp_diff match failure
regexp "^  LOAD[ \t]+0x[0-9a-f]+ 0x0*40000000 0x0*40000000 0x[0-9a-f]+ 0x[0-9a-f]+ R E 0x[0-9a-f]+$"
line   "  LOAD           0x000054 0x40000000 0x40000000 0x0000c 0x0000c RWE 0x4"
FAIL: ld-elf/orphan-region

But it also fails the same way with -N for i686-pc-linux-gnu so I assume 
this is simply an expected consequence of using -N.  With this patch 
applied to adjust the expectation as well as using -N, it passes for both 
c6x-elf and i686-pc-linux-gnu.  OK to commit?

	* ld-elf/orphan-region.d: Use ld -N.
