[PATCH] TC_START_LABEL_WITHOUT_COLON

[Timothy Wall]

This patch adds a macro check equivalent to TC_START_LABEL in the case
where LABELS_WITHOUT_COLONS is defined.  This gives the target a chance
to check the label if labels do not require colons.

* gas/read.c (read_a_source_file):  Add TC_START_LABEL_WITHOUT_COLON to
give parallel functionality as TC_START_LABEL when LABELS_WITHOUT_COLONS
is defined.
