As others have said, no, it should have no effect on the icache, at
least on systems I know (mainly ELF). The debug section isn't even
loaded into memory at runtime, it's just sitting there eating disk
until someone like gdb comes along and reads it explicitly.

With my Linux distribution packager hat on, though, I wouldn't mind if
the default were changed. I'd change it back so I could provide
out-of-band debug symbols in my packages, but overriding CFLAGS at
build time is so trivial that anyone doing any special handling like
this shouldn't really be inconvenienced.
