build: fix LLVM version detection
The regex match used for detecting the LLVM version works for versions
with a single-digit major number. Now that LLVM v10 is out, detection
can fail, resulting in sparse-llvm not being built.
Fix detection by extracting the major version number to compare with the
minimum supported.
