[PATCH] powerpc: Fix unitialized variable

[Adhemerval Zanella]

The 'resolv/res_send.c' build with _STRING_ARCH_unaligned not defined
may utilize the local resplen uninitialized.  This patch sets it to 0.

Tested on powerpc64 and powercp32. Along with the e_lgammal_r patch,
it fixes the powerpc warning build with werror.
