Salutations,

For mpv, waf is installed to build the package (it's in the makedepends
array). It's not needed to run the program though.

I think what your recommendation boils down to is adding a jobs string
that specified how many jobs to run independent of the compiler. It
would be difficult to balance the unique flags of different compilers
with a universal flag in makepkg.conf. That may be opening a can of
worms (if compilers use different flags to specify the threading).

Regards,
Mark
