libtool: allow tabs in *_cmds variables

Browse Source 
This is in preparation for the next patch, which needs to have literal
tab characters survive the evaluation of the *_cmds variables.

build-aux/ltmain.in (func_execute_cmds, func_mode_link): Don't collapse
tabs and surrounding whitespace into a single space when executing a
tilde-separated cmds construct, instead keep any tabs intact.
