um: Use char[] for linker script address declarations
The linker script defines some variables which are declared either with type char[] in include/asm-generic/sections.h or with a meaningless integer type in arch/um/include/asm/sections.h. Fix this inconsistency by declaring every variable char[]. Signed-off-by: Nicolas Iooss <nicolas.iooss_linux@m4x.org> Signed-off-by: Richard Weinberger <richard@nod.at>
