The problem is that with -ffunction-sections -fdata-sections gcc
creates sections like .text.head and .data.nosave
whenever someone has innocuous code like this:
static void head(...) {...}
or this:
static int nosave = 1;
somewhere in the kernel. Currently, kernel linker scripts
are confused by such names and put these sections in wrong places.
