[xml] build from source and *-config executable permission

[Roumen Petrov <bugtrack roumenpetrov info>]

Hi All,

Version of 1.2.13 of xmlsec add support to build from libxml2/libxslt 
source and this is good reason to setup a build environment where all 
packages are kept up-to-date. After synchronization to recent repository 
version user can just type make in build directory and the make rules 
will do his job just fine with one exception: if configure.in script is 
updated the *-config files are recreated but lost executable permission.

The attached file bootstrap.sh with simple GNU autotool based build show 
how to reproduce and avoid issue.

As the patch is quite trivial I would like to describe only how to fix 
issue without to propose a diff-file.

- libxml2/configure.in:
move line "chmod +x xml2-config python/setup.py" before AC_OUTPUT in a 
AC_CONFIG_COMMANDS macro, i.e.:
AC_CONFIG_COMMANDS([set_executable], [chmod +x xml2-config python/setup.py])
AC_OUTPUT(....

- libxslt/configure.in:
the script don't set executable flag of xslt-config when is created.
so the solution: AC_CONFIG_COMMANDS before AC_OUTPUT as exapmle
AC_CONFIG_COMMANDS([set_executable], [chmod +x xslt-config])


Regards,
Roumen
