Hans Beckérus - Sept. 14, 2013, 9:01 a.m.
This patch updates libtool.m4 (and its output) to resolve a problem 
with variable 'lt_sysroot' not being properly updated if the option
'--with[-libtool]-sysroot' is not provided when running the 'configure'
script for a package.

According to the help text ouput from 'configure':
--with-libtool-sysroot=DIR Search for dependent libraries within DIR
                        (or the compiler's sysrooot if not specified).

Due to mixed up cases in a switch statement, when checking if the option
was specified or not, wrong actions were taken resulting in an incorrect
sysroot and failures to properly locate e.g. .la files when using the 
populated SDK toolchain.

For current upstream status see:
http://lists.gnu.org/archive/html/bug-libtool/2013-09/msg00005.html

My world build passed without errors (besides a lot of missing or unbuildable dependency chains and one or two that failed to download completely). I believe this is about all the testing I can do from my end, especially considering my limited computer power.

Thanks.
Hans
