Compile with -fno-omit-frame-pointer

[Daimrod]

GCC >= 4.6 use -fnomit-frame-pointer by default, but without frame pointers the name of the fonction and its arguments won't appear in the backtrace.

with -fno-omit-frame-pointer: http://pastebin.com/KKVMFNZT

I've tested on every version from 1.0.20 to 1.0.50 from the git repo with the default configuration and gcc 4.6.1

According to the gcc documentation this option his only available on x86-32.

    add -fno-omit-frame-pointer to x86 builds

      GCC >= 4.6 omits it by default, leading to broken backtraces.
