[LTP] Test case float_trigo Reading dsin error

[fixed-term.Islam.Tammam]

I have faced recently an issue with an imx6 target which is running 
kernel version "3.14" for the below tests:

float_bessel
float_exp_log
float_power
float_trigo

these tests are failing and giving an error of thread termination "No 
such file or directory". Please find a log below. any reason why that 
happened and how can this be solved ?

target:/opt/ltp/testcases/bin# ./float_trigo
float_trigo 1 TPASS : Test passed
float_trigo 1 TFAIL : main.c:292: thread 100 (sin) terminated
unsuccessfully 0 errors/0 loops
FAIL: sin: reading dsin, No such file or directory
float_trigo 2 TFAIL : main.c:292: thread 101 (sin) terminated

float_trigo 3 TFAIL : main.c:292: thread 102 (sin) terminated
unsuccessfully 0 errors/0 loops
FAIL: sin: reading dsin, No such file or directory
float_trigo 4 TFAIL : main.c:292: thread 103 (sin) terminated

float_trigo 40 TFAIL : main.c:292: thread 139 (tan) terminated
unsuccessfully 0 errors/0 loops
FAIL: tan: reading dtan, No such file or directory
float_trigo 41 TFAIL : main.c:41: Test failed

I have no idea why the generation of files such asin, atan, acos works 
but doesn't work for dsin and dtan ?
