[PATCH] um: fix strrchr problems

[Richard Weinberger]

From: Al Viro <viro@xxxxxxxxxxxxxxxx>

[richard@xxxxxx:
Fixes:
/usr/lib/gcc/x86_64-linux-gnu/4.4.5/../../../../lib/libc.a(strrchr.o): In function `rindex':
(.text+0x0): multiple definition of `strrchr'

If both STATIC_LINK and UML_NET_VDE are set to "y" libc's strstr
may clash with the kernel implementation.

This workaround comes originally from Jeff Dike:
