Currently, the syntax of attribute(address-space()) accept
an identifier as well as the usual 'address space number'.
However, developers with a recent version can't benefit
of the display of address spaces by name before the kernel
definition of __user is changed.
To let early adopters to already benefit, allow to specify
the address names via the command line (which ignore unknown
options and is thus forward compatible): -faddress-space-names.
