'make clean' or 'rm tools/*/_*.h' as workaround didn't works, problem 
still happen.
I already use git reset --hard and git git clean -f -d -x before any 
test that clean all except other git repos (seabios, ovmf and qemu).
I missed to tell I use also a change I did for workaround in Config.mk:
PYTHON_PREFIX_ARG ?= --prefix="$(prefix)" to PYTHON_PREFIX_ARG ?=

Probably it in combination with one or more ./configure options that 
have a regression.
I'm testing with this: 
https://github.com/Fantu/Xen/commits/rebase/m2r-staging and was working 
until https://github.com/Fantu/Xen/commits/rebase/m2r-next
Is simply a rebase and only the first patch had a conflict for this 
commit: 7f5f57b466b026d19cacfe7fc5771895d05a053b
The regression should be between upstream commit 
f48218fd2d35e274ef58caee889aecd6610c8cb6 and 
ecdae1cfaa7f6123decaa1b9d7205c3ff726b941

Without problem tools/libxl/_paths.h is correctly generated:

With the problem instead:

I'm still trying various combinations but I have a problem to found the 
exactly parameters that cause the problem, some restult are 
strange...I'm going crazy :(
During testing I had also this:

> ovmf.c:100:21: error: Ãovmfà undeclared (first use in this function)

Probably because I tried before with build ovmf and after with prebuild 
from system that cause an inexpected case.
