* config/i386/i386.c (processor_target_table): Increase maximum
skip from 7 byte to 10 byte for Pentium Pro, Core 2 Duo and
default 64bit.
* config/i386/linux.h (ASM_OUTPUT_MAX_SKIP_ALIGN): Ensure 8
byte alignment if > 8 byte alignment is preferred.
* config/i386/x86-64.h (ASM_OUTPUT_MAX_SKIP_ALIGN): Likewise.
