This directive, which is available for ELF targets, marks each symbol in
the comma-separated list of
names as a local symbol so that it
will not be externally visible. If the symbols do not already exist,
they will be created.
For targets where the
.lcomm directive (see Lcomm) does not
accept an alignment argument, which is the case for most ELF targets,
.local directive can be used in combination with
(see Comm) to define aligned local common data.
