Leo Yan 7eec00a747 perf symbols: Consolidate symbol fixup issue 
After copying Arm64's perf archive with object files and perf.data file
to x86 laptop, the x86's perf kernel symbol resolution fails.  It
outputs 'unknown' for all symbols parsing.

This issue is root caused by the function elf__needs_adjust_symbols(),
x86 perf tool uses one weak version, Arm64 (and powerpc) has rewritten
their own version.  elf__needs_adjust_symbols() decides if need to parse
symbols with the relative offset address; but x86 building uses the weak
function which misses to check for the elf type 'ET_DYN', so that it
cannot parse symbols in Arm DSOs due to the wrong result from
elf__needs_adjust_symbols().

The DSO parsing should not depend on any specific architecture perf
building; e.g. x86 perf tool can parse Arm and Arm64 DSOs, vice versa.
And confirmed by Naveen N. Rao that powerpc64 kernels are not being
built as ET_DYN anymore and change to ET_EXEC.

This patch removes the arch specific functions for Arm64 and powerpc and
changes elf__needs_adjust_symbols() as a common function.

In the common elf__needs_adjust_symbols(), it checks an extra condition
'ET_DYN' for elf header type.  With this fixing, the Arm64 DSO can be
parsed properly with x86's perf tool.

Before:

  # perf script
  main 3258 1 branches:                0 [unknown] ([unknown]) => ffff800010c4665c [unknown] ([kernel.kallsyms])

  main 3258 1 branches: ffff800010c4eebc [unknown] ([kernel.kallsyms]) => ffff800010c4ed80 [unknown] ([kernel.kallsyms])

After:

  # perf script
  main 3258 1 branches:                0 [unknown] ([unknown]) => ffff800010c4665c coresight_timeout+0x54 ([kernel.kallsyms])

v3: Changed to check for ET_DYN across all architectures.

v2: Fixed Arm64 and powerpc native building.
