--- Comment #105 from Olivier Certner <olce@FreeBSD.org> ---
Same here:

> XPCOMGlueLoad error for file /usr/local/lib/firefox/libgkcodecs.so:
> /usr/local/lib/firefox/libgkcodecs.so: Undefined symbol "sin"
> Couldn't load XPCOM.

with CPUTYPE x86-64-v3. Goes away with the runtime workaround of comment #9 or
the first attached patch at build.

By the way, for those wanting to use a "sensible" CPUTYPE supporting several
different machines, I can only recommend using the psABI-defined levels, such
as 'x86-64-v3', which have been supported by GCC and clang for a few years now.
For a summary, see, e.g.,
https://en.wikipedia.org/wiki/X86-64#Microarchitecture_levels.
