[Issues] Math functions for DBL-64 with LIBM_BIG is disabled


Hi There,
I am seeing the following failures when building eglibc for x86-64 using a limited set of options, specifically with OPTION_EGLIBC_LIBM enabled and OPTION_EGLIBC_LIBM_BIG disabled.
It seems that the configuration time is not setting the paths correctly and the math functions are still looking for the optimized versions provided by the LIBM_BIG option. 

Thanks
