With this patchset I can build and run make check on arm-linux-gnueabihf
with lld 13.0. I see 12 regressions, however I think it something
related to lld instead of a glibc issue:

The lld does not support R_ARM_GOTOFF32 to preemptible symbol (_dl_argv
has global visibility). Use the internal alias instead (one option
would to use HIDDEN_JUMPTARGET, bu the macro is not defined for
!__ASSEMBLER__ and I made this patch arm-specific to avoid require to
check extensivelly on other architecture it this might break something).
Checked on arm-linux-gnueabihf.

The lld linker does not support TLSDESC for arm. The have-arm-tls-desc
is a leftover of 56583289b1 to support NaCL.

The linker might add another section between the two relocation section
for the loader as well. For instance on arm, lld does:
[ 7] .rel.dyn REL 000007f0 0007f0 000088 08 A 1 0 4
[ 8] .ARM.exidx ARM_EXIDX 00000878 000878 0000b0 00 AL1 2 0 4
[ 9] .rel.plt REL 00000928 000928 000028 08 AI 1 17 4
This patch removes the ELF_DURING_STARTUP optimization and assume
both section might no be linear.
Checked on x86_64, i686, aarch64, armhf, powerpc64le, powerpc64,
and powerpc (to check if this breaks on different architectures).

Following up the discussion on glibc call, below it an update of the
patch description.

The patch removes the the ELF_DURING_STARTUP optimization and assume
both .rel.dyn and .rel.plt might no be linear. This allows some
code simplification since relocation will be handled independently
where it done on bootstrap.
I could not see any performance implications, at least on x86_64.
Running 10000 time the command
LD_DEBUG=statistics ./elf/ld.so ./libc.so
And filtering the "total startup time in dynamic loader" result,
the geometric mean I see are:
patched master
Ryzen 7 5900x 24140 24952
i7-4510U 45957 45982
(the results do show some variation, I did not make any statistical
analysis).
It also allows build arm with lld, since it inserts ".ARM.exidx"
between ".rel.dyn" and ".rel.plt" for the loader.
Checked on x86_64-linux-gnu and arm-linux-gnueabihf.
