Building i386 on RED Hat

[Joel Sherrill]

Two problems.

1.  bit_rtems is normally invoked "bit_rtems CPU BSP".  Otherwise you
build all BSPs with "bit_rtems CPU". Most people do not want to do this.

1a.  ts_386ex won't link because the i386 toolset does not have
soft-float
support.  The patch it depended on was against egcs and broke other
things.
I have worked on a solution to this and the next (snapshot) RPMs include
an attempt at soft-flot support and will at least link this BSP.

2.  The compilation stopped because there is a typo in
c/src/lib/libbsp/i386/i386ex/startup/linkcmds.
