35	Options include:
36	    --arch=ARCH            architecture to compile for ($arch)
37	    --processor=PROCESSOR  processor to compile for ($arch)
38	    --vmm=VMM              virtual machine monitor to compile for (qemu
39	                           or kvmtool, default is qemu) (arm/arm64 only)
40	    --cross-prefix=PREFIX  cross compiler prefix
41	    --cc=CC		   c compiler to use ($cc)
42	    --ld=LD		   ld linker to use ($ld)
43	    --prefix=PREFIX        where to install things ($prefix)
44	    --endian=ENDIAN        endianness to compile for (little or big, ppc64 only)
45	    --[enable|disable]-pretty-print-stacks
46	                           enable or disable pretty stack printing (enabled by default)
47	    --[enable|disable]-default-environ
48	                           enable or disable the generation of a default environ when
49	                           no environ is provided by the user (enabled by default)
50	    --erratatxt=FILE       specify a file to use instead of errata.txt. Use
51	                           '--erratatxt=' to ensure no file is used.
52	    --host-key-document=HOST_KEY_DOCUMENT
53	                           Specify the machine-specific host-key document for creating
54	                           a PVM image with 'genprotimg' (s390x only)
55	    --page-size=PAGE_SIZE
56	                           Specify the page size (translation granule) (4k, 16k or
57	                           64k, default is 64k, arm64 only)
58	    --earlycon=EARLYCON
59	                           Specify the UART name, type and address (optional, arm and
60	                           arm64 only). The specified address will overwrite the UART
61	                           address set by the --vmm option. EARLYCON can be one of
62	                           (case sensitive):
63	               uart[8250],mmio,ADDR
64	                           Specify an 8250 compatible UART at address ADDR. Supported
65	                           register stride is 8 bit only.
66	               pl011,ADDR
67	               pl011,mmio32,ADDR
68	                           Specify a PL011 compatible UART at address ADDR. Supported
