xtoolchain-llvm10 missing?

[Ronald Klop]

Hi,

Building CURRENT on my laptop takes very very long because every little  
change in llvm/clang makes it recompile a complete compiler. So I want to  
build with CROSS_TOOLCHAIN=xtoolchain-llvm10 (10.0) and  
WITHOUT_TOOLCHAIN=yes.
In ports/pkgs the most recent versions I see are xtoolchain-llvm90 or  
xtoolchain-llvm-devel (11.0?).
Is xtoolchain-llvm10 missing on purpose?

Regards,
Ronald.
