Works fine for me:

const char foo[] = "test";

$ cc -fPIC -c x.c
$ objdump --headers x.o

.rodata contains the symbol, as it should; the only other section with a
size != 0 is the magical .note.

Note that on ELF, .text is not the only read-only section.  There are
several possible ones; .rodata is actually supposed to be mapped read-only
and *non-executable* where possible.  8-)
