ruby -v: ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]
Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN


=begin
mkmf.rb's pkg_config modifies $LDFLAGS after 2.0.0 (r35605 ?) like the following:

 # ruby 1.9.3p392 (2013-02-22 revision 39386) [x86_64-linux]
 p $LDFLAGS #=> "-L.  -rdynamic -Wl,-export-dynamic"
 p pkg_config('libxml-2.0') #=> ["-I/usr/include/libxml2  ", "", "-lxml2  "]
 p $LDFLAGS #=> "-L.  -rdynamic -Wl,-export-dynamic "
 
 # ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]
 p $LDFLAGS #=> "-L. -fstack-protector -rdynamic -Wl,-export-dynamic"
 p pkg_config('libxml-2.0') #=> ["-I/usr/include/libxml2", "", "-lxml2"]
 p $LDFLAGS #=> "-lxml2 "
 
 
 # 2.0.0 + my patch
 p $LDFLAGS #=> "-L. -fstack-protector -rdynamic -Wl,-export-dynamic"
 p pkg_config('libxml-2.0') #=> ["-I/usr/include/libxml2", "", "-lxml2"]
 p $LDFLAGS #=> "-L. -fstack-protector -rdynamic -Wl,-export-dynamic "

attached patch fixes this to 1.9.3 behaviour.

I'll commit this if there's no problem.
