JExtract unknown type name 'intmax_t' for /usr/include/yara.h

[Maurizio Cimadamore]

Hi,
this issue seems to be related to the fact that the jextract gradle 
build did not fail, despite the LLVM path being used not containing all 
the bells and whistles that the jextract build requires.

So, a possible quality of life improvement here would be to add some 
more sanity checks on the build, to check that the structure of the LLVM 
folder is as expected. IIRC, the structure of the apt-installed LLVM 
does not 100% match that of a LLVM binary snapshot.

Cheers
Maurizio
