Makefile: Add new option COMPAT_GETOPT

This new option controls if compat/getopt.c should be compiled and linked
into lspci and setpci binaries. Useful for ancient platforms.

For example it is required to set COMPAT_GETOPT=yes for all versions of
MinGW32 with CRTDLL (as this MinGW32 variant does not have linkable
getopt() implementation). And also for MinGW32 with MSVCRT older than 3.0.
