orbea a34555c9a9 qb: Include /usr/local/include for bsd based systems.
This resolves an issue where the default freebsd compiler does not
include /usr/local/include which contains important headers such as
GL/gl.h and results in the check_header function failing to find them.

Unfortunately pkg-config/pkgconf will not work here for two reasons.
1. It does not seem able to actually check for gl.h which RetroArch
explicitly needs.

2. Not all systems have a pkg-config implementation so we will still
have to fall back to checking for gl.h...
