$ grep -r LL_ALIGN_POSTFIX linden/indra/* | grep '#define'

linden/indra/llcommon/llmemory.h:#define LL_ALIGN_POSTFIX(x) __attribute__((aligned(x)))
linden/indra/llcommon/llmemory.h:#define LL_ALIGN_POSTFIX(x)
linden/indra/llcommon/llmemory.h:#define LL_ALIGN_16(var) LL_ALIGN_PREFIX(16) var LL_ALIGN_POSTFIX(16)

You probably failed to #include "llmemory.h" in the sources where this
error happens.
