can not build xf86-video-intel

[Łukasz Gruner]

Hi,

Recently I switched from using ports only to packages and now trying to
enable kms.

I've rebuild libdrm, but xf86-video-intel fails with the following error
(any ideas how to fix that?):

  CC     sna_display_fake.lo
  CC     sna_driver.lo
sna_driver.c:437:2: error: implicit declaration of function
'xf86getBoolValue' is invalid in C99
[-Werror,-Wimplicit-function-declaration]
        xf86getBoolValue(&val, xf86GetOptValString(sna->Options, id));
        ^
