Hi,

when using the commit 47394d05017483e7fd0cba5b927c76198bdfa062 
(https://github.com/Freescale/meta-freescale/commit/47394d05017483e7fd0cba5b927c76198bdfa062), 
set IMX_DEFAULT_BSP="nxp" and the distro fsl-xwayland-distro I see error 
of configuration of mesa. This is reproduces on latest master of 
meta-freescale.

This is the error I see in do_configure step of xserver-xorg:

     No package 'dri' found

The root cause of this is that dri.pc file is not produced and put in to 
sysroot by mesa. Mesa does not provide this as the configuration option 
'-Ddri-drivers' is empty. In the recipe it is set as:

     PACKAGECONFIG[dri] = 
"-Ddri-drivers=${@strip_comma('${DRIDRIVERS}')}, -Ddri-drivers='', 
xorgproto libdrm"

Before commit 47394d050 DRIDRIVERS was set to swrast but after the 
variable is empty. Can someone help out  with a way forward?

Steps to reproduce:

     $ MACHINE=imx8mp-evk DISTRO=fslc-xwayland EULA=1 . 
./setup-environment build_imx8mp-evk
     $ echo "IMX_DEFAULT_BSP = 'nxp'" >> conf/auto.conf
     $ bitbake xserver-xorg -cconfigure

     Build Configuration:
     BB_VERSION           = "1.49.0"
     BUILD_SYS            = "x86_64-linux"
     NATIVELSBSTRING      = "ubuntu-20.10"
     TARGET_SYS           = "aarch64-fslc-linux"
     MACHINE              = "imx8mp-evk"
     DISTRO               = "fslc-xwayland"
     DISTRO_VERSION       = "3.3-snapshot-20210129"
     TUNE_FEATURES        = "aarch64 armv8a crc cortexa53 crypto"
     TARGET_FPU           = ""
     meta
     meta-poky            = 
"master:24e95b9a0b0610dd82aa85f0c0c6fb4f347bc3e9"
     meta-oe
     meta-multimedia
     meta-python          = 
"master:fd123c9bb2b86455ca2622b6b166243f7d582d94"
     meta-freescale       = 
"master:9a90b21cbe32231fee51c7f38e541b3be3aff6b3"
     meta-freescale-3rdparty = 
"master:d46200f43537083762dca518dc2ba7f20d15f44f"
     meta-freescale-distro = 
"master:e83f54d0b763826f076e8aed1fc16dbf5b2739e5"

Thanks,
/Peter
