| Subject: [PATCH 06/12] libtool.m4: Handle "/" as a sysroot correctly |
| |
| Update libtool.m4 to resolve a problem with lt_sysroot not being properly |
| updated if the option '--with[-libtool]-sysroot' is not provided when |
| running the 'configure' script for a package so that "/" as a sysroot |
| is handled correctly by libtool. |
