I cannot reproduce the multiple definition from current eCos CVS using
the at91sam7sek target and setting CYGNUM_HAL_ARM_AT91_CLOCK_TYPE ==
"EXTCLOCK".

So CYGNUM_HAL_RTC_NUMERATOR is defined by the variant HAL and this
suppresses the fallback definition of CYGNUM_HAL_RTC_PERIOD in kernel.h.

Try saving your configuration to a new location and building from scratch.

I hope this helps...
