[avr-libc-dev] [bug #57071] Fix math.h and function names that block 64-bit double

[Georg-Johann Lay]

Follow-up Comment #1, bug #57071 (project avr-libc):


        * include/math.h
        (cos, sin, tan, fmod, modf, sqrt, cbrt, hypot, square, floor, ceil)
        (frexp, ldexp, exp, cosh, sinh, tanh, asin, acos, atan, atan2)
        (log, log10, pow, isnan, isinf, signbit, fdim, fma, fmax, fmin)
        (trunc, round, lround, lrint) [double=64-bit]: Provide double
        prototypes.
        [double=32-bit]: Provide protos with assembler names which are
        the corresponding float function name.

        (cosf, sinf, tanf, fmodf, modff, sqrtf, cbrtf, hypotf, squaref)
        (floorf, ceilf, frexpf, ldexpf, expf, coshf, sinhf, tanhf, asinf)
        (acosf, atanf, atan2f, logf, log10f, powf, isnanf, isinff)
        (signbitf, fdimf, fmaf, fmaxf, fmin, truncf, roundf, lroundf)
        (lrintf):
        Turn from macro to proper prototype.
        (fabs, fabsf, isfinite, isfinitef, copysign, copysignf): Implement.

        * libm/fplib/acos.S: Use correct names for functions that deal
        with float, e.g. acosf instead of acos.  Adjust comments.
