libyasm/section.c: support gas .private_extern directive (#138)
Support for "private_extern" was previously added for nasm mode via
a declaration like so:
global foo:private_extern
foo:
; codes
However, that same code in gas format looks like this:
.private_extern foo
foo:
# codes
Add support for the gas version of "private_extern" syntax by
supporting a new gas `.private_extern` directive that actually
has exactly the same semantics as the nasm `global ...:private_extern`
directive.
