On Linux, this introduces yet another symbol to blacklist.

8c23d3a5df Make Windows symbol-prefixing work.
This teaches read_symbols.go to use debug/pe, and fixes miscellaneous
issues with NASM. It also reveals a problem with this strategy of
getting symbols out at the linker level: inline functions.  I'm thinking
a better long-term mechanism may be to parse our header files.

1a0f908e92 Move __.SYMDEF handling to ar.go.
One less bit of special-casing in read_symbols.go. We filter out the
sysv-style symbol table, so we should filter out the macOS one too.

Add tests for util/ar to cover this and the Linux case.

8b0dad4a7f Don't double-mangle C++ symbols on macOS.
The symbol-listing code already removes the leading underscore.

abbc59896f Make read_symbols.go a bit more idiomatic.
It's more verbose, but trimming the panics should make it easier to move
to a library (e.g. a symbol checker) or unit test later.
