Subject: [PATCH] Arc: fix entry point calculation for locales other than english

The problem was detected while making uImage.
To find the line with entry point address in the result
of the "readelf -h vmlinux" command "grep ENTRY POINT" is used.

But if the operating system locale is not english,
command readelf returns lines in local language.

Grep cannot find the line which contains "ENTRY POINT" in english.
Our decision uses readelf key which displays the symbol table.
Using grep _stext it finds the line with entry point in this table.
