MIPS: Support `-gnuabi64' target triplet suffix for 64-bit Linux targets
Make the n64 ABI the default for 64-bit Linux targets specified with

There are the following regressions with the new target triplet:
The `readelf' issue comes from a difference in section headers produced
that the `binutils/testsuite/binutils-all/readelf.s-64' pattern template

me that there is a clear advantage from adding more and more variations

PR10957, Missing option to really print section+offset
Many of the reloc error messages have already been converted from
using %C to using %H in ld.bfd, to print section+offset as well as
file/line/function. This catches a few remaining, and changes gold to
do the same.

elf_object_p load of dynamic symbols
This fixes an uninitialised memory access on a fuzzed file:
0 0xf22e9b in offset_from_vma /src/binutils-gdb/bfd/elf.c:1899:2
1 0xf1e90f in _bfd_elf_get_dynamic_symbols /src/binutils-gdb/bfd/elf.c:2099:13
2 0x10e6a54 in bfd_elf32_object_p /src/binutils-gdb/bfd/elfcode.h:851:9
Hopefully it will also stop any attempt to load dynamic symbols from
eu-strip debug files.
* elfcode.h (elf_object_p): Do not attempt to load dynamic
symbols for a file with no section headers until all the
program headers are swapped in. Do not fail on eu-strip debug
files.
gprofng: 30602 [2.41] gprofng test hangs on i686-linux-gnu
There were several problems in the gprofng testing:
- we did not catch a timeout for each test.
- we used exit() to stop a failed test. But this stops all other tests.
- we used a time_t (long) type in smalltest.c instead of a long long type.
