Description of problem:
Some (new?) abi modules are not built due to CONFIG_ABI_XXX name change. 
ie:

Version-Release number of selected component (if applicable): 2.4.16-0.13

How reproducible: Always

Steps to Reproduce:
copy kernel-2.4.16-ix86.config to .config, make menuconfig, select abi, 
save config, see differences.
	
Actual Results:  abi-isc not built (maybe others)

Expected Results:  abi-isc should be built

Additional info:
default config contains
    CONFIG_ABI_IBCS_ISC=y
    # CONFIG_ABI_ISC is not set
while the correct way is now:
    CONFIG_ABI_ISC=m

same for solaris, maybe others
