Maximilian Brune 23f0b0b313 util/xcompile/xcompile: Fix clang target parameter ...

It updates the target variable that is used for `clang -target`.
Simply because the format was wrong. According to the documentation the
format of the so called "target triple" is:
<arch><sub>-<vendor>-<sys>-<env>
with:
arch = x86_64, i386, arm, thumb, mips, etc.
sub = for ex. on ARM: v5, v6m, v7a, v7m, etc.
vendor = pc, apple, nvidia, ibm, etc.  (can be omitted)
sys = none, linux, win32, darwin, cuda, etc.
env = eabi, gnu, android, macho, elf, etc.

In case of powerpc that causes an issue when trying to update clang to
version 21. The target parameter for clang ends up being
"powerpc64-none-unknown-linux-gnu". After testing, it turns out that in
clang version 18 that is actually a valid target parameter, although not
according to the documentation. In clang 21 however its not valid so fix
it accordingly.
