NACK.

Developers working on Linux distributions have no interest
in your homebrew setup.

For 99% of users, pkg-config does not do anything good.
It is a waste of process forks.



You need to do it outside.


 $ HOSTCFLAGS=$(pkg-config --cflags bee-headers) make

or

 $ export HOSTCFLAGS=$(pkg-config --cflags bee-headers)
 $ make
