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 '.'.

Make it executable like it should be. Do the same for other files intended to be
executed by the user - the ones called by the build process needn't be
executable as they already work (as argument to their interpreter).

This is a rewrite of Andi Kleen's bloat-o-meter with sorting and reporting of
gainers/decliners. Sample output:
add/remove: 0/8 grow/shrink: 2/0 up/down: 88/-4424 (-4336)
function old new delta
__copy_to_user_ll 59 103 +44
__copy_from_user_ll 59 103 +44
fill_note 32 - -32
maydump 58 - -58
dump_seek 67 - -67
writenote 180 - -180
elf_dump_thread_status 274 - -274
fill_psinfo 308 - -308
fill_prstatus 466 - -466
elf_core_dump 3039 - -3039
The summary line says:
no functions added, 8 removed
two functions grew, none shrunk
we gained 88 bytes and lost 4424 (or -4336 net)
