pci_drivers/cpu_drivers: Fix constructed arrays on x86_64
The __pci_driver and __cpu_driver uses variable length arrays which are
constructed by the linker at build-time.
The linker always place the structs at 16-byte boundary, as per
"System V ABI". That's not a problem on x86, as the struct is exactly
16 Bytes in size. On other platforms, like x86_64 it breaks, because the
default data alignment isn't SysV compatible.
Set -malign-data=abi to make x86_64 gcc use the SysV psABI.
Fixes broken __pci_driver and __cpu_driver on x86_64.
