RFC: section merge test (ld-elf)

[Sivanupandi, Pitchumani]

Hi,

Tests flags1.s and merge.s (ld/testsuite/ld-elf) are XPASS for AVR.
AVR target seems to merge similar sections into single segment. But AVR
target was marked as xfail in these tests.

Test flags1.s expects output (after objcopy) have one program header. But
sections are merged to a segment while linking itself (same for native
as well). Is that expected from this testcase?
Is that testcase intended to check merge of sections after objcopy with
updated flags?

Regards,
Pitchumani
