makefile_engine: can't build 64bit drivers

[X512]

This is hrev53780 x86_64.

When building test driver on x86_64, link fails:

cc -o "objects.x86_64-cc8-release/acpi_test"    objects.x86_64-cc8-release/acpi_test.o  -nostdlib /boot/system/develop/lib/_KERNEL_ /boot/system/develop/lib/haiku_version_glue.o  -L./

If add -fPIC to compiler options, drivers compiles, but don't load, bad data error is written in syslog.
