Subject: maint: rename the debug shell command variable to `debug_cmd'.
X-Git-Tag: v2.4.2.418~302
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=db48cd3e2b9463414520d9fd439c0e30246a7cc7;p=thirdparty%2Flibtool.git

maint: rename the debug shell command variable to `debug_cmd'.

Not only does it make more sense, it also matches bootstrap and
others.
* libtoolize.m4sh, libltdl/config/ltmain.m4sh,
libltdl/config/getopt.m4sh, tests/defs.m4sh (opt_debug): Rename
to debug_cmd.
