Saying --enable-llvm=/home/jo/lib or --enable-llvm=/home/jo/bin gives me

...
checking for valgrind.h... (cached) no
checking for dsymutil... no
dsymutil is not available
checking for dsymutil... no
dsymutil is not available
configure: error: You must specify valid path to your LLVM tree with
--enable-llvm=DIR

quite early in 'make'.

--enable-llvm=/home/jo does a lot more work before it finally hits the
assembler problems.

So I conclude that --enable-llvm should point to wherever --prefix
pointed when LLVM was built, and the assembler problem have some other
source.
