XCOFF C_STSYM test failure on 32-bit host
This test was failing here and on another similar symbol:
[ 4](sec 1)(fl 0x00)(ty 0)(scl 143) (nx 0) 0x05d1745d11745d21 .bs
where correct output is
[ 4](sec 1)(fl 0x00)(ty 0)(scl 143) (nx 0) 0x000000000000000a .bs
The problem is caused by a 32-bit host pointer being sign-extended
when stored into a 64-bit bfd_vma, and then that value not being
trimmed back to 32 bits when used. The following belt-and-braces
patch fixes both the store and subsequent reads.
* coffcode.h (coff_slurp_symbol_table): Do not sign extend
when storing a host pointer to syment.n_value.
* coffgen.c (coff_get_symbol_info): Cast syment.n_value to a
bfd_hostptr_t before using in arithmetic.
(coff_print_symbol): Likewise.
