Log Message:
Force a full dependency on libpciaccess in situations where we definitely
need to link with it but might have included x11/xf86driproto's bl3.mk first,
because we have:
x11/xf86driproto/buildlink3.mk:BUILDLINK_DEPMETHOD.libpciaccess?=  build

(This issue appears only on non-x86 because on x86 we get libpciaccess
 through libdrm)

Bump PKGREVISION to get the dependency expressed.
