Use -mrtd and -mregparm=3 to reduce the generated code sizes.
	This means that any missing prototypes could be fatal. Also, you
	must take care when writing assembly code. See the comments at
	the beginning of startup.S, for more details.

	* kern/i386/pc/startup.S (pupa_halt): Modified for the new
	compilation mechanism.
	(pupa_chainloader_real_boot): Likewise.
	(pupa_biosdisk_rw_int13_extensions): Likewise.
	(pupa_biosdisk_rw_standard): Likewise.
	(pupa_biosdisk_check_int13_extensions): Likewise.
	(pupa_biosdisk_get_diskinfo_int13_extensions): Likewise.
	(pupa_biosdisk_get_diskinfo_standard): Likewise.
	(pupa_get_memsize): Likewise.
	(pupa_get_mmap_entry): Likewise.
	(pupa_console_putchar): Likewise.
	(pupa_console_setcursor): Likewise.
	(pupa_getrtsecs): Use pushl instead of push.

	* kern/i386/pc/init.c (pupa_machine_init): Use the scratch
	memory instead of the stack for a mmap entry, because some
	BIOSes may ignore the maximum size and overflow.

	* conf/i386-pc.rmk (COMMON_CFLAGS): Added -mrtd and -mregparm=3.

	* genmk.rb (PModule#rule): Compile automatically generated
	sources with module-specific CFLAGS as well as other sources.
