Comment (by ross@…):

 In an attempt to have less magic I added the flags line to gcc.jam in
 build:


 {{{

 index 270ca97..f31f4ef 100644

 instruction_set, values, default=

 ['-mx32'])
  flags('gcc', 'OPTIONS', ['<architecture>x86/<address-model>64'],
 ['-m64'])
 }}}

 Then passed address-model=32_64 to my externally built jam (we're cross-
 compiling).

 It's passing less stupid options now:


 {{{

 "libs/regex/build/../src/winstances.cpp"
 }}}

 Now it fails differently:

 {{{
 libs/context/src/unsupported.cpp:7:2: error: #error "platform not
 supported"
  #error "platform not supported"
 }}}

 Presumably because this new 32_64 address-model doesn't match the build
 rules for context which use a 64-bit address-model but abi to mark x32:


 {{{
 # X86_64/SYSV/X32
 alias asm_context_sources
    : [ make asm/make_x86_64_sysv_elf_gas.o :
