Remove `pow10` for now; CHECK_MATH_FUNC needs work

The CHECK_MATH_FUNC() m4 macro needs work.  It should use
AC_RUN_IFELSE(), not just AC_LINK_IFELSE(), and it should #define
_GNU_SOURCE and/or other such feature macros in the prologue to get
non-standard math functions (alternatvely jq should only support
standard math functions).
