gas: missing (re-)initialization of local variable in fixup_segment()
At the very least this has been causing bogus diagnostics, e.g.
.text
.data
.long .bss - .
.long -.text
.bss
yielding
Error: can't resolve `0' {.bss section} - `.text' {.text section}
instead of
Error: can't resolve `0' {*ABS* section} - `.text' {.text section}
In particular for targets overriding any of TC_FORCE_RELOCATION_* & Co
or for ones setting md_register_arithmetic to true the problems may be
worse.
