PowerPC: remove wrong truncl implementation for PowerPC64
The truncl assembly implementation (sysdeps/powerpc/powerpc64/fpu/s_truncl.S) returns wrong results for some inputs where first double is a exact integer and the precision is determined by second long double. Checking on implementation comments and history, I am very confident the assembly implementation was based on a version before commit 5c68d401698a58cf7da150d9cce769fa6679ba5f that fixes BZ#2423 (Errors in long double (ldbl-128ibm) rounding functions in glibc-2.4). By just removing the implementation and make the build select sysdeps/ieee754/ldbl-128ibm/s_truncl.c instead it fixes tgammal issues regarding wrong result sign.
