[Buildroot] [PATCH] gpsd: Replace the deprecated finite function with the isfinite macro

[Markos Chandras]

Quote from the finite() man page:
"Note that these functions are obsolete. C99 defines macros isfinite(),
isinf(), and isnan() (for all types) replacing them.  Further note that
the C99 isinf() has weaker guarantees on the return value.  See
fpclas-sify(3)."

The finite() function is not supported by recent versions of uClibc
