[yocto] packageconfig for non-autotooled project

[Trevor Woerner]

Hello,

libepoxy needs its EGL support to have a packageconfig (*.pc) file but
the EGL I want to use in my project
(meta-sunxi/recipes-graphics/libgles/sunxi-mali_git.bb, which points to
gitsm://github.com/linux-sunxi/sunxi-mali.git) isn't autotooled. There
are a couple ways around this problem, but if there is an example of
generating a .pc file for a non-autotooled project already, I'd be
grateful if someone could point me to it :-)

Best regards,
    Trevor
