Ok, the "&" generation can be avoided by rewriting the configure section 
from line 20073 to line 20083 and removing the commas between "-Wl" and 
"$ldflags" like:
"""
ldflags=
if test yesyes = "$GXX$enable_shared" ; then
  case $host_os in
    *mingw* | *cygwin*)
      ldflags="--enable-runtime-pseudo-reloc"
      if $CXX -Wl $ldflags 2>&1 >/dev/null|grep -e $ldflags >/dev/null 
2>&1; then
                                    { { echo "$as_me:$LINENO: error: ld 
version too old to support a shared build - configure with 
--disable-shared, or install binutils 2.13.90-20030111-1 or later" >&5
echo "$as_me: error: ld version too old to support a shared build - 
configure with --disable-shared, or install binutils 2.13.90-20030111-1 
or later" >&2;}
   { (exit 1); exit 1; }; }
      fi
      ldflags="-Wl $ldflags"
    ;;
  esac
fi
"""
xapian-config then generates immediatly.

Then I got another error : make cannot find any rule to build 
xapian-config.1. This is because I am not compiling in "maintainer mode" 
and therefore xapian-config.1 generation is skipped, see Makefile.in bottom:
"""
@MAINTAINER_MODE_TRUE at xapian-config.1: xapian-config
@MAINTAINER_MODE_TRUE@    $(HELP2MAN) -o xapian-config.1 --no-info -S 
"$(PACKAGE_STRING)" -n "`sed 's/^PROG_DESC=\"\(.*\)\".*/\1/p;d' 
$(srcdir)/xapian-config`" ./xapian-config
"""

Unfortunately, xapian-config.1 is referenced by "man_MANS" which is left 
uncommented and triggers the make error. I solved it manually by editing 
directly the generated Makefile. I guess the following section should be 
compiled conditionally (Makefile.in (291)):
"""
man_MANS = xapian-config.1
MAINTAINERCLEANFILES = $(man_MANS)
"""
But it might trigger other dependency errors...

Now, it is libtool turn to complain:

Removing the examples from build targets solves this but you may be 
interested by this issue. I would be happy to help but right now I 
prefer to get xapian python bindings to compile.

Thank you for your help, I will try the bindings right now.
