bloat-o-meter: avoid double counting
Disable 'echo' in the default config, run 'make baseline', then
re-enable 'echo' and run 'make bloatcheck':
function old new delta

The Total bytes value doesn't equal the change in the size of the
binary. The packed_usage and applet_* items are in .rodata and
are counted twice. With this modified bloat-o-meter the size of
named items is deducted from .rodata:
function old new delta

applet_main 3168 3176 +8
.rodata 105105 105113 +8

(add/remove: 0/0 grow/shrink: 6/0 up/down: 101/0) Total: 101 bytes
text data bss dec hex filename

v2: Sections numbered less than 10 were always being omitted from
consideration because splitting "[ 1] .interp" leaves "1]" in
x[1] where the section name is expected. This wasn't a problem
for .rodata (numbered 15 in my testing) but let's fix it anyway.
