[PATCH] fix bloat-o-meter for ppc64

[Nathan Lynch <ntl@pobox.com>]

bloat-o-meter assumes that a '.' anywhere in a symbol's name means
that it is static and prepends 'static.' to the first part of the
symbol name, discarding the portion of the name that follows the '.'.
However, the names of function entry points begin with '.' in the
ppc64 ABI.  This causes all function text size changes to be accounted
to a single 'static.' entry in the output when comparing ppc64
kernels.

Change getsizes() to ignore the first character of the symbol name
when searching for '.'.
