Guys, in case anybody figures out what's wrong in baselibs.conf of Mesa
package, please let me know. Sigh.

After reading the baselibs.conf documentation [1] it seems there are two
different statements that are extremely similar and are confused within the
Mesa baselibs.conf.

The two statements being:

- arch <arch> package <package>
- arch <arch> targets <target_arch>[:<target_type>]

The first being used to apply only to <package> when arch is <arch>. The
second being used to control the arch and target_arch combinations applied
when evaluating the baselibs.conf file.

Given that the missing requirements should not be requirements of Mesa-libd3d-
devel-32bit and are not dependencies of Mesa-libd3d-devel.x86_64 it seems that
the parser is interpreting the arch lines as matching the second form (or
ignoring as invalid) rather then a conditional to the lines below them.

requires "Mesa-libd3d-<targettype> = <version>"
arch aarch64 ppc64 ppc64le s390x x86_64 package libvulkan_intel
arch aarch64 ppc64 ppc64le s390x x86_64 package libvulkan_radeon
arch aarch64 ppc64 ppc64le s390x x86_64 package Mesa-libVulkan-devel
requires "libvulkan_intel-<targettype> = <version>"
requires "libvulkan_radeon-<targettype> = <version>"

Since they happen to be placed after Mesa-libd3d-devel they are applied to it
as if written without the arch lines:

requires "Mesa-libd3d-<targettype> = <version>"
requires "libvulkan_intel-<targettype> = <version>"
requires "libvulkan_radeon-<targettype> = <version>"

From the documentation there does not appear to be a conditional for multiple
archs. Instead the only option appears to be targettype in front of each line.
This obviously requires repeating for each arch which is a bit ugly. Short of
reading the parser to confirm this appears to be the only option.

Feel free to rework my request 516907 [2] as needed. Looking at the build
results it properly removes the dependencies from Mesa-libd3d-devel-32bit

It would seem possible for the parser to look for the "package" keyword and
allow for the desired syntax. I would imagine it either ignored those lines or
using the second syntax (with the target keyword).
