On ARM, binutils are adding '$a' symbols in the symbol table for
every function (in addition to normal symbol). When gprof(1) looks
up symbol name, it often reads '$a' instead of proper function name,
because it find it first. With this fix, when read symbol name
begins with '$' and previous symbol has the same address, it will
use previous symbol name (which is proper function name).

Discussed with: imp, rwatson
on allocation failure instead of displaying a warning and deferencing NULL
pointer after. Spelling. Add prototypes. Add list of option in synopsis section
of man page, -d is not referenced because available as a compile option. It
should be made a runtime option btw.
