# Libtool:

libtoolize --force --copy
#
# Используется если в configure.ac вызывается LT_INIT.
# Patch необходим по тому, что и lib-ld.m4 и libtool.m4
# используют функцию AC_ARG_WITH([gnu-ld], ...
# а это приводит к тому, что ./configure --help дважды
# выдает подсказку --with-gnu-ld :
#
patch -p0 < $CWD/config/patches/libtool.m4.patch
patch -p0 < $CWD/config/patches/libtool.m4-shared.patch
 
#
# End of Libtool.
