add -fno-finite-math-only in KOPT_CFLAGS

Browse Source 
In some compilation platform if finite-math-only option is turned
on, math functions like exp and sqrt will be dynamically linked to
finite versions which cannot be located in Kindle's GLIBC. In my
toolchain the symbol __exp_finite cannot be found in GLIBC_2.4 so
gcc just use __exp_finite in GLIBC_2.15, which will cause a run time
error in Kindle saying "version GLIBC_2.15 not found"
