kgdb: Replace strstr() by strchr() for single-character needles

Some versions of gcc replace calls to strstr() with single-character
"needle" string parameters by calls to strchr() behind our back.
This causes linking errors if strchr() is defined as an inline function
in <asm/string.h> (e.g. on m68k, which BTW doesn't have kgdb support).

Prevent this by explicitly calling strchr() instead.
