Package: mesa
Version: 20.2.1-1

In debian\rules, there is the following at lines 74-79:

ifneq (,$(filter $(DEB_HOST_ARCH), amd64 i386 x32)) GALLIUM_DRIVERS += ,svga,zink # svga needs xa state tracker confflags_GALLIUM += -Dgallium-xa=true VULKAN_DRIVERS += ,intel endif

When this is parsed on x32, the value of VULKAN_DRIVERS is blank. This puts a , at the start of the variable, which breaks the build using meson.

This works on other platforms as earlier the AMD driver is added (see lines 54-56).

From the buildd logs, the CFLAGS passed are:
CFLAGS="-g -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -Wformat -Werror=format-security -Wall" CPPFLAGS="-Wdate-time -D_FORTIFY_SOURCE=2" CXXFLAGS="-g -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -Wformat -Werror=format-security -Wall" FCFLAGS="-g -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong" FFLAGS="-g -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong" GCJFLAGS="-g -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong" LDFLAGS="-Wl,-z,relro" OBJCFLAGS="-g -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -Wformat -Werror=format-security" OBJCXXFLAGS="-g -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -Wformat -Werror=format-security"  dh_auto_configure -- \

Notably from that:
     -Dvulkan-drivers=",intel"

Suggest that lines 74-79 need to be modified to check if the VULKAN_DRIVERS variable already has some value set or not, or treat x32 as a special case, before adding ",intel" or "intel" to the VULKAN_DRIVERS variable as appropriate.

Note: I don't have an x32 build env. I just saw the failed buildd logs via the debian Mesa tracker.

Changes:
 mesa (20.3.0-2) experimental; urgency=medium
