From the origin commit message:
Regression from 2.4.2 was causing noticable slow-down in builds
that call libtool many times.
* build-aux/ltmain.in (func_help): Override func_help() from
gl/build-aux/options-parser to only run automake --version and
autoconf --version when libtool --help is executed on the command
line.

This reverts commit 1f53edeaf9ea59dd55459a6d5a93829fb4983839.
There is a better fix on upstream, will backport it.

Cut and paste the pieces of build-aux/options-parser inline into the main
ltmain.sh code. This removes a performance degradation caused by the
repeated calls to func_quote_for_eval, the mechanism funclib uses
to construct the functions used for option parsing.

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.

If for example you build on a machine with /bin/grep, then restore that sstate
onto a machine with /usr/bin/grep, things will fail. Simply don't bother
hardcoding paths.
This was lost during the libtool upgrade:
http://git.yoctoproject.org/cgit.cgi/poky/diff/meta/recipes-devtools/libtool/libtool/avoid_absolute_paths_for_general_utils.patch?id=d4e1862453b2a4c12400de0f43f08a9871a4de60
since the path to the files changed. This restores the previous behaviour.
