Patch 1 causes the following linker tests to fail on s390 64-bit (s390x):
FAIL: Build libgot_64-1.so
FAIL: TLS -fpic -shared transitions
FAIL: TLS -fpic and -fno-pic exec transitions
FAIL: SFrame simple link
FAIL: SFrame for plt0 and pltN
FAIL: Empty SFrame section

Patch 2 causes most of the new linker test fails to go away, while the
following remain:

FAIL: SFrame simple link
FAIL: SFrame for plt0 and pltN

Both due to missing GNU_SFRAME program header, causing section headers
and sections (including .text) to start at a different address.

I suggest you swap the order of both patches, so that patch 2 comes
before patch 1.  Not sure how to resolve the missing GNU_SFRAME program
header.

Regards,
Jens
