-a in that sense is an argument to build-dep and family (source --build,
satisfy). It is short for host-architecture, and makes no sense in any
other command.
You seem to be trying to install libfontconfig-dev:i386
We haven't explained that it works outside of source --compile and
build-dep (i.e. in satisfy) but I fail to see how you get to try
to pass this to install after reading the manual page.
The help output obviously can't tell you which commands support
which arguments.
