XCOFF assembly defines the visibility using an additional argument
on several pseudo-ops: .globl, .weak, .extern and .comm.
This implies that .globl and .weak syntax is different than the
usual GNU syntax. But we want to provide compatibility with AIX
assembler, especially because GCC is generating the visibility
using this XCOFF syntax.
