This is the first part of a series reducing user-mode
dependencies. By stripping out unused code, the build
and testing time is reduced (as is space used by objects).

Part 1:
- reduce user-mode object list
- remove some migration code from user-mode
- remove cpu_get_crash_info()

What is the purpose of dividing into parts? What is the content of other parts, and when do you plan to submit those? A series is usually a stand-alone and a complete logical unit - why did you decide to submit "parts" separately (just curious)?

Does this series affect executables' size, or cut build times only?


Since v1:
- Addressed Laurent/Richard review comments
- Removed 'exec: Drop redundant #ifdeffery'
- Removed 'target: Restrict write_elfXX_note() handlers to system-mode'

v1: https://www.mail-archive.com/address@hidden/msg688456.html

  Makefile: Only build virtiofsd if system-mode is enabled
  configure: Avoid building TCG when not needed
  tests/Makefile: Only display TCG-related tests when TCG is available
  tests/Makefile: Restrict some softmmu-only tests
  util/Makefile: Reduce the user-mode object list
  stubs/Makefile: Reduce the user-mode object list
  target/riscv/cpu: Restrict CPU migration to system-mode
  exec: Assert CPU migration is not used on user-only build
  arch_init: Remove unused 'qapi-commands-misc.h' include
  target/i386: Restrict CpuClass::get_crash_info() to system-mode
