There is no need to compile our DLLs as shared libraries since we are
managing symbols exports and imports through spec files.
On my system, this reduces the configure-time by a factor of two.
This should fix some virtual machines and real hardware machine with empty floopy drive
not being able to boot ReactOS (stuck while initializing floppy.sys).
This fixes a regression introduced in r70746.
It could be generalized to other interrupts, floppy controllers not being reliable.
