  57 # If there is more than one syscall list for different architecture
  58 # variants, the CPU/Makefile defines abi-variants to be a list of names
  59 # for those variants (e.g. 32 64), and, for each variant, defines
  60 # abi-$(variant)-options to be compiler options to cause <asm/unistd.h>
  61 # to define the desired list of syscalls and abi-$(variant)-condition to
  62 # be the condition for those options to use in a C #if condition.
  63 # abi-includes may be defined to a list of headers to include
  64 # in the generated header, if the default does not suffice.
  65 #
  66 # The generated header is compiled with `-ffreestanding' to avoid any
  67 # circular dependencies against the installed implementation headers.
  68 # Such a dependency would require the implementation header to be
  69 # installed before the generated header could be built (See bug 15711).
  70 # In current practice the generated header dependencies do not include
  71 # any of the implementation headers removed by the use of `-ffreestanding'.
