eglibc: modified option-groups.h generation 

option-groups.h only explicitely #defines options that are enabled.
EGLIBC options are typically pre-processed under the assumption that if
an option is not explicitely defined then it evaluates as 0.
This assumption is correct, but it generates a compiler warning
message each time an undefined symbol is being evaluated.
In order to remove the warnings, each EGLIBC option is now defined
as 1 if the option is enabled or as 0 otherwise.
The consequence is we cannot use #ifdef OPTION_XXX when evaluating
the option, we must always use #if OPTION_XXX.

[YOCTO #7001]
