stdlib/tst-strtod-round.c: Fix build on ARM
Building this test on ARM fails because the prototypes for the long double variants of the math functions are unavailable. Add an additional include guard to math.h that enables long double math function declarations if _LIBC_TEST is defined and define _LIBC_TEST in stdlib/tst-strtod-round.c. ChangeLog: 2014-09-30 Will Newton <will.newton@linaro.org> * math/math.h: Define long double math functions if _LIBC_TEST is defined. * stdlib/tst-strtod-round.c: Define _LIBC_TEST.
