libtool: avoid running automake/autoconf --version
The libtool would be very slow if run "automake/autoconf --version", for
example, when compile xz-native (make -j1, only compile, no confiure or
install):
before patched: 19s
after patched: 11s
Use plain text to instead of running them.
NOTE: it is still a little slower than libtool 2.4.2 when compile
xz-native because of other parts:
make -j1: about 2s slower
make -j32: about 0.4s slower
If we run to do_install:
(PARALLEL_MAKE = "-j32")
libtool 2.4.2:
$ bitbake xz-native -cinstall && bitbake xz-native -ccleansstate && time bitbake xz-native -cinstall
real 0m21.092s
user 0m28.292s
sys 0m3.932s
libtool 2.4.5:
$ bitbake xz-native -cinstall && bitbake xz-native -ccleansstate && time bitbake xz-native -cinstall
real 0m21.380s
user 0m31.140s
sys 0m4.068s
About 0.3s, slightly different.
But when using /bin/bash as CONFIG_SHELL, the new libtool would be much slower:
real 0m23.106s
user 0m44.044s
sys 0m4.280s
About 2s slower, for the big package like cairo, it is more slower (about 6s),
unfortunately, /bin/bash is most default CONFIG_SHELL for the recipes since
configure checks first check bash.
