Provide a more flexible mechanism for specifying which modules are loaded.

Now three classes are defined: 'request', 'auto', and 'asm_ok'. The 'auto'
class is loaded automatically if the platform support matches up with
what we are building for (this is the former default). The 'request' mode
means it is only loaded if specifically requested by name. The 'asm_ok'
module is marked for all modules that use any assembler (including inline
assembler). This normally functions like 'auto', unless --debug is passed
to configure, in which case it is treated as 'request'.

Modules which do not specify a load behavior are given a default of
'request'.
