[PATCH] bootgraph: fix for use with dot symbols

[Michael Neuling <mikey@neuling.org>]

powerpc has dot symbols, so the dmesg output looks like:
 
<4>[    0.327310] calling  .migration_init+0x0/0x9c @ 1
<4>[    0.327595] initcall .migration_init+0x0/0x9c returned 1 after 0 usecs

The below fixes bootgraph.pl so it handles this correctly.
