Any tries to get proper options or env settings to ./configure failed.
I finally hacked the generated Makefile to carefully prepend every
reference to /usr/local by /usr/local/libxml2 within any include path
and any loader path. 

Here the modified lines : 

CPPFLAGS = -I/usr/local/libxml2/include
EXTRA_LDFLAGS = -avoid-version -module 
-Wl,-R/usr/local/libxml2/lib:/usr/local/lib -L/usr/local/libxml2/lib 
-L/usr/local/lib -L/usr/lib/mysql
EXTRA_LDFLAGS_PROGRAM =  -Wl,-R/usr/local/libxml2/lib:/usr/local/lib 
-L/usr/local/libxml2/lib -L/usr/local/lib -L/usr/lib/mysql
INCLUDES = [...] -I/usr/local/libxml2/include 
-I/usr/local/libxml2/include/libxml2 -I/usr/local/include 
-I$(top_builddir)/TSRM -I$(top_builddir)/Zend
NATIVE_RPATHS = -Wl,-rpath,/usr/local/libxml2/lib -Wl,-rpath,/usr/local/lib 
-Wl,-rpath,/usr/lib/mysql
PHP_LDFLAGS =  -Wl,-R/usr/local/libxml2/lib:/usr/local/lib 
-L/usr/local/libxml2/lib -L/usr/local/lib -L/usr/lib/mysql
PHP_RPATHS = -R /usr/local/libxml2/lib -R /usr/local/lib -R /usr/lib/mysql 

May thanks to Ken and Luc for the help.
