The testcases still introduce new failures.
alpha-linux-gnu  +FAIL: ld-elf/textaddr10
h8300-linux-gnu  +FAIL: ld-elf/textaddr8
microblaze-linux-gnu  +FAIL: ld-elf/textaddr10
microblaze-linux-gnu  +FAIL: ld-elf/textaddr9

alpha because the testsuite adds -Ttext-segment.  h8300 with a RWE
segment starting at 0x800000, combining .text and .data.  microblaze
also mashes .text and .data together.  None of these are your problem,
so the patch is OK.
