OK.

If I correctly understand cvs comment in OpenBSD ports, OpenBSD
started to use _GLOBAL_OFFSET_TABLE_ when binary format is switched to
elf.

Because output of ld -V should contain "elf_i386_obsd" in "Supported
emulations" section on elf x86 OpenBSD releases, I think configure
script can use this behavior to determine that which symbol name
should use.

How about this?

if !(${LD} -V | egrep 'elf_i386_obsd' > /dev/null); then
echo 'define(<_GLOBAL_OFFSET_TABLE_>, <__GLOBAL_OFFSET_TABLE_>)' >>$gmp_tmpconfigm4
fi
