Subject: scripts/faddr2line: Set LANG=C to enforce ASCII output
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=567f9c428f99560fe14e647def9f42f5344ebde9;p=thirdparty%2Fkernel%2Flinux.git

scripts/faddr2line: Set LANG=C to enforce ASCII output

Force tools like readelf to use the POSIX/C locale by exporting LANG=C
This ensures ASCII-only output and avoids locale-specific
characters(e.g., UTF-8 symbols or translated strings), which could
break text processing utilities like sed in the script
