Fix missing symbols for crash reports because -exx was incorrectly added to build_info

FB 1.07 changed __FB_ERR__ so that any fbc -g builds (which includes pdb=1
builds) had -exx in the build info, so wrong symbols were downloaded and
backtraces couldn't be decoded.

Just assume that -exx in any affected crash reports is wrong. Noone uses debug
builds anyway.

I also added FB_ERR (__FB_ERR__) to build_info.
