When compiling the latest master (also happens on 2.0.0 release), the compile fails with the following:

/bin/sh ../libtool  --tag=CC   --mode=link gcc -Wall -fvisibility=hidden    -module -avoid-version -no-undefined -Wl,--no-undefined   -o i965_drv_video.la -rpath /usr/lib64/va/drivers  libi965_drv_video.la -lpthread -lm -ldl -ldrm  -ldrm_intel  -lm

Using libva from git.

Is GCC 8.0 distributed by any distro at this point?
