#475 native-elf-format have to enforce locale

[Alexander Cherepanov]

While building on GNU/Linux systems with non-English locale, common/native-elf-format fails to parse readelf output and cannot generate a proper common/native-elf-format.h.

Attached patch was enough for me but perhaps locale should be enforced for the whole building process.

[Ed Maste]

It seems reasonable to me to enforce it within native-elf-format as a user may run the script manually to test.
