This is a fallout from r484697. MythTV 29.1 bundles FFmpeg 3.2 because
VDPAU support relies on deprecated[1] API removed[2] in 4.0. As LOCALBASE
on FreeBSD isn't treated as -isystem by default[3] this make -I order
important e.g., -I/usr/local/include -I. will pick system headers
instead of bundled. Unfortunately, converting to USES=localbase:ldflags
doesn't help here because the port doesn't respect C*FLAGS when building
that file. And I couldn't figure out where C*FLAGS are overriden.
