bfd: xtensa: fix callx relaxation
Big section alignment requirements between source and destination of a
long call can result in making call range bigger than what's reachable
by the call opcode. Add biggest section alignment of sections between
the call site and call destination to the call distance when making
long call relaxation decision.

bfd/
* elf32-xtensa.c (is_resolvable_asm_expansion): Scan output
sections between the call site and call destination and adjust
call distance by the largest alignment.
ld/
* testsuite/ld-xtensa/call_overflow.d: New test definition.
* testsuite/ld-xtensa/call_overflow1.s: New test source.
* testsuite/ld-xtensa/call_overflow2.s: New test source.
* testsuite/ld-xtensa/call_overflow3.s: New test source.
* testsuite/ld-xtensa/xtensa.exp: Add call_overflow test.
