Adding -fno-omit-frame-pointer to www/chromium/Makefile gives a build
error in poudriere:
../../third_party/ffmpeg/libavcodec/x86/mpegaudiodsp.c:84:5: error:
'asm' operand has impossible constraints

     ^

or did you add this flag to devel/libexecinfo/Makefile?

The other option would be to conditionally zero out the return value if
/usr/lib/libexecinfo.so does not exist.
