[PATCH v3 00/12] user-mode: Prune build dependencies (part 1)

[PATCH v3 00/12] user-mode: Prune build dependencies (part 1)

[Philippe Mathieu-Daudé]

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

This series is fully reviewed.

Since v2:
- Rebased due to conflict when applying patch:
  "util/Makefile: Reduce the user-mode object list"
  because commit 01ef6b9e4e modified util/Makefile.objs:
  "linux-user: factor out reading of /proc/self/maps"

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

[PATCH v3 02/12] configure: Avoid building TCG when not needed

Avoid building TCG when building only tools:

  ./configure --enable-tools --disable-system --disable-user

This saves us from running the soft-float tests enabled since
commit 76170102508.

[PATCH v3 04/12] tests/Makefile: Restrict some softmmu-only tests

[Philippe Mathieu-Daudé]

In the next commit we are going to remove some objects from the
util-obj-y variable (objects which are not used by user-mode,
when configured with --disable-system).
Then some system-mode tests are going to fail, due to the missing
objects:

[PATCH v3 04/12] tests/Makefile: Restrict some softmmu-only tests

Then some system-mode tests are going to fail, due to the missing
