    makesyscalls: Add a way to include per-ABI headers
    
    When the string %%ABI_HEADERS%% is found in syscalls.master, replace
    it with the contents of the abi_headers config variable.  This allows
    an ABI-specific syscalls.conf to add lines like:
    
            #include <compat/freebsd32/freebsd32.h>
    
    when working from a shared syscalls.master.
