package/mesa3d: fix aarch64_be build

Browse Source 
Buildroot commit 1b8d7e7bed bumped the
package to version 23.2.1 that contains the upstream commit
77826e8352 (e65744354fdd7dd38342b138e59e40767cfcdaa9)
which causes build errors on aarch64_be.

The build error was first seen by the autobuilders with mesa3d-23.3.3:
https://autobuild.buildroot.net/results/b62/b62eba2155b080ed02fde774994f2fffc8a6ef51/
according to https://autobuild.buildroot.net/?reason=mesa3d-25.3.4&arch=aarch64_be

A backport to LTS branches should be considered.
