Subject: [PATCH] MIPS: Fix computation on entry point

Since commit 27c524d17430 ("MIPS: Use the entry point from the ELF
file header"), the kernel entry point is computed with a grep on
"start address" on the output of objdump. It works fine when the
default language is english but it may fail on other language (for
example in French, the grep should be done on "adresse de départ").
To fix this computation on most machine, I propose to force the
language to english with "LC_ALL=C".

Fixes: 27c524d17430 ("MIPS: Use the entry point from the ELF file header")
