libm: add missing symbols to optimized math functionsstaging/cm-12.0-caf
add the following missing symbols to optimized math functions:
sqrtl => sqrt
sinl => sin
cosl => cos
these symbols will be weak references to the functions at
right-hand side when compiler internal macro
(__LDBL_MANT_DIG__ == 53) is true
