Hi,

Here is an updated patch.

Changes between v4 and v5:
* Added sanity checks for powerpc64 and xtensa
(--enable-non-contiguous-regions does not work with relaxation), to
emit an error message rather than crash
* Removed a bogus assert in size_input_section
* Added quotes around section names in error messages
* Updated tests:
- ld-arm/non-contiguous-arm[25] now pass on arm-nacl
- ld-arm/non-contiguous-arm[36] are now skipped on arm-nacl because
the stub code is different from the expected one and a dedicated test
didn't seem mandatory
- ld-arm/non-contiguous-arm4 updated expected error message
- ld-elf/non-contiguous: do not require little-endian, accept both
endiannesses, discard target-specific sections to make expected output
matching possible. Skip on xtensa where relaxation is enabled by
default and conflicts with the new option
- ld-powerpc/non-contiguous-powerpc: skip on powerpc64 (because the
error message is different)
- ld/powerpc/non-contiguous-powerpc64: new test, with the error
message expected on powerpc64
* Squashed all patches into one

Tested for non-regression on the list of 163 targets provided by Alan.
I left the error on mep-elf, because many other tests fails on that
target with the same error message (selected target format
'elf32-mep-little' unknown)
