[Nbd] error compiling nbd 2.9.15 with enable-debug

[Richard Huddleston <rhuddusa@...17...>]

i'm trying to debug some nbd segfaults

nbd-server[7256]: segfault at 0 ip 0000000000402879 sp
00007fff11ce8060 error 4 in nbd-server[400000+7000]

and so i thought i'd try compiling with debugging

i'm trying to compile nbd 2.9.15 with --enable-debug
on ubuntu lucid 64 bit
