[Qemu-devel] [PATCH v2 1/2] Makefile: Set default locale C

[Stefan Weil <sw@weilnetz.de>]

Some locale settings let make fail or create wrong results,
so set always the C locale.

* Conversion from lower to upper case with tr does not convert
  lower case 'i' to 'I' with locale tr_TR.UTF-8. This results in
  wrong entries in config-host.h like these ones:

  #define CONFIG_QEMU_PREFiX "/usr/local"
  #define CONFIG_QEMU_BiNDiR "/usr/local/bin"

  This problem was reported by Emre Ersin.

* The html files created from texi input contain non english
  titles like "Anhang" with locale de_DE.UTF-8.

The locale variables are not explicitly exported here to avoid
possible problems with the 'export' keyword. Either they are
already environment variables when make is called - then the
new values are passed to child processes, or there are no such
environment variables - then the default value C is used.

v2:
Enhanced commit message.
