We have a problem in that in making compatibility checks while merging
private BFD data on the MIPS target we give priority to the attribute
check, which may fail and cause the function to abort early on. The
problem with this is the ABI compatibility aspect recorded in the
attributes is relatively minor compared to aspects recorded in the ELF
file header. However the premature exit causes any more important
compatibility aspect violated to be masked and not reported to the user
once a problem with attributes has been noticed.
So move the attribute check after the ELF file header flag check in
`_bfd_mips_elf_merge_private_bfd_data', and do not return prematurely
there. Take advantage of the resulting grouping of ELF file header
handling together and remove the premature success return point for the
first input object being handled, letting the code later on figure out
output ABI flags even for this object.
Update LD test cases according to messages from ELF file header checks
now preceding ones from attribute checks.

Fold the handling of input MIPS ABI flags in private BFD data merging
together, moving the attribute check afterwards, and consequently making
input vs output compatibility checks only start once all input ABI flag
data has been gathered, checked for inconsistencies and put in order.
Consequently also address the issue of input ABI flag inconsistencies
being masked by a failing attribute check, which currently makes
`_bfd_mips_elf_merge_private_bfd_data' exit prematurely and therefore
prevent input ABI flag inconsistencies from being reported. Such
inconsistencies need to be reported as they may be the very cause of an
attribute check failure.
bfd/
* elfxx-mips.c (_bfd_mips_elf_merge_private_bfd_data): Fold the
handling of input MIPS ABI flags together.
We currently special-case the handling of attribute checks on input
objects and make them even before we check a given input object actually
contains any sections. This does not add value as empty objects do not
cause a compatibility concern and we already make this observation for
other properties such as ELF file header flags. Moreover the attributes
themselves are stored in a `.gnu.attributes' section so the absence of
any section (except from a few special cases) implies there have been no
attributes provided either. Therefore it is safe to move the attribute
checks later on, after the null-section check has been made.

For the case of MIPS n64 target and 32-bit host, the computation of
the DT_MIPS_RLD_MAP_REL tag involves sdyn->output_section->vma +
sdyn->output_offset (64-bit) being added to b (32-bit host pointer),
so losing the high part and resulting in an incorrect
DT_MIPS_RLD_MAP_REL tag, and all dynamically linked glibc tests
failing for n64. This patch fixes this (spot-tested with glibc tests;
however, I don't have a self-contained testcase for this bug).

Copy relocs are used in a scheme to avoid dynamic text relocations in
non-PIC executables that refer to variables defined in shared
libraries. The idea is to have the linker define any such variable in
the executable, with a copy reloc copying the initial value, then have
both the executable and shared library refer to the executable copy.
If the shared library defines the variable as protected then we have
two copies of the variable being used.
