It turns out that using nm -P isn't as portable as hoped. In particular with some ELF ABIs (e.g. ppc64 ELFv1), the desired symbols end up in the data section instead of text. The test is currently only functional on ELF based architectures, so I think it's legit to depend on readelf instead of nm. The switch to readelf has the advantage that we can explicitely ask for all of the symbols with global visibility, rather than grepping for notmuch. That seems a more robust approach since it will catch any strangely named global symbols.
