Compare LLVM_VERSION_SHORT to "140" rather than "14".
In commit 2b07721, support was added to p-libcxx.inc & p-llvm.inc
for LLVM versions 14+ (in which, apparently, certain build flags
were changed). To detect these recent versions, the variable
LLVM_VERSION_SHORT was compared numerically to "14"-- the intent
obviously being to express "LLVM version 14 or later".

However, in both v-clang.inc & v-llvm.inc, LLVM_VERSION_SHORT
is defined as the concatenation of LLVM_VERSION_MAJOR and
LLVM_VERSION_MINOR. Therefore, on a machine with, say, LLVM
13.0 installed, LLVM_VERSION_SHORT will be "130" which compares
as larger than "14".

This patch changes the comparison to be against "140".
