remove GNU specific nm option from version script

[Matthias Guedemann]

hi all,

I compiled notmuch on OpenBSD and stumbled onto the usage of the GNU
specific option "--defined" to nm.

I replaced this with calling nm without options and then filtering the
output with grep

tried on OpenBSD 5.0 -current and Debian on current git head

regards
Matthias
