syntax-check: fix violations and implement sc_useless_braces_in_variable_derefs.
Until now, libtool sources have used braced variable names
seemingly at random! Almost always the braces are just noise, so
remove all the unnecessary ones.
* cfg.mk (sc_useless_braces_in_variable_derefs): New syntax
check rule to ensure we only reintroduce braced variable
dereferences if they are followed by a valid variable name
character.
