[PATCH 2/3] libtool: unify the global symbol transformations

[Peter Rosin]

Since it is safe for $lt_cv_sys_global_symbol_to_cdecl to match
with a simple /^T .* .*$/ type expression, it is ok for the other
transformations as well.  At least if you require at least one
$symcode at the start of the line, so that the just generated output
doesn't match the next sed expression.

* m4/libtool.m4 (_LT_CMD_GLOBAL_SYMBOLS): Unify the matching expressions
in the sed programs that transform the extracted symbol lines.
