* sysdeps/powerpc/powerpc32/power6/fpu/s_copysign.S: Add compat symbol
copysignl for GLIBC_2_0.
* sysdeps/powerpc/powerpc32/power7/fpu/s_finite.S: Add compat symbol
finitel for GLIBC_2.0 and __finitel for GLIBC_2_1.
* sysdeps/powerpc/powerpc32/power7/fpu/s_logb.c: Add compat symbol
logbl for GLIBC_2_0.
* sysdeps/powerpc/powerpc64/power6/fpu/s_copysign.S: Likewise.
