On armel, long double is same the type as a double, and thus tgamma()
and tgammal() are the same functions. On x86 long double and double are
different types, and thus tgamma() and tgammal() are different
functions.
Your test code with long double and tgammal() on armel gives as expected
exactly the same result as double and tgamma() on x86. I don't see any
problem here, this function works as expected.
