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.
