IBM Z: Fix pcrel relocs for symA-symB expressions
The code in md_apply_fix which tries to deduce from the operand type
which reloc to apply currently does the wrong thing for absolute
relocs which have been re-written by fixup_segment as pc-relative to
implement a subtraction of a local and an external symbol.
In all these cases we wrongly emit an absolute reloc because we ignore
the fx_pcrel flag in md_apply_fix. However, only for the last one we
actually support a pc relative relocation of the proper size and can
implement it accordingly. For the other 3 we have to issue an error.
foo:
cli 0(%r2),undef-foo
la %r2,undef-foo(%r2)
lay %r2,undef-foo(%r2)
lhi %r2,undef-foo
