Adding new board support option

[Peter Dufault]

I'm adding a new board support option.  I put this in c/src/lib/libbsp/ 
powerpc/mpc55xxevb/configure.ac:

RTEMS_BSPOPTS_SET([HAS_SMC91111],[*],[0])
RTEMS_BSPOPTS_HELP([HAS_SMC91111],
[Define to 1 if the board has the SMC91111 chip.])

and put this in c/src/lib/libbsp/powerpc/mpc55xxevb/Makefile.am:
if HAS_SMC91111
network_rel_SOURCES += network/if_smc.c
endif

but:

[dufault at finny mpc55xxevb]$ autoreconf
Makefile.am:73: HAS_SMC91111 does not appear in AM_CONDITIONAL
autoreconf: /opt/rtems-4.10/bin/automake failed with exit status: 1
[dufault at finny mpc55xxevb]$

What step am I missing?
