Subject: scripts/bloat-o-meter: add -p argument

When doing cross platform development on a machine sometimes it might be
useful to invoke bloat-o-meter for files which haven't been build with the
native toolchain. In cases when the host nm doesn't support the target
one then a toolchain-specific nm could be used. Add this ability by
adding the -p allowing invocations as:
./scripts/bloat-o-meter -p riscv64-unknown-linux-gnu- file1.o file2.o
