[igt-dev] [PATCH i-g-t] Introduced partial FreeBSD compatibility

Hi there,

I am considering bundling all FreeBSD-specific igt macros into an
`igt_freebsd.h` header
for greater accessibility. If this idea is acceptable, I need a place to
create this file.
What's the appropriate location for an igt-specific header that does not
have a corresponding
source file?

Thank you,
Jake Freeland
