We create a separate header file for link symbols defined by the link
scripts. It is helpful to have these all in one place and try to
make them common across architectures. Since Linux already has a similar
file, we bring this in even though many of the symbols there are not
relevant to us.
Each architecture has its own asm/sections.h where symbols specifc to
that architecture can be added. For now everything except AVR32 just
includes the generic header.
One change is needed in arch/avr32/lib/board.c to make this conversion
work.

Note this is a tree-wide change affecting multiple architectures.
At present we use __bss_start, but mostly __bss_end__. This seems
inconsistent and in a number of places __bss_end is used instead.
Change to use __bss_end for the BSS end symbol throughout U-Boot. This
makes it possible to use the asm-generic/sections.h file on all
archs.

This is available on other architectures, and nds32 will start to break
without it as code starts to use error numbers more.

We plan to move architecture-specific data into a separate structure so
that we can make the rest of it common.
As a first step, create struct arch_global_data to hold these fields.
Initially it is empty.
This patch applies to all archs at once. I can split it if this is really
a pain.

This doesn't need to be a long, so change it.
Also adjust bi_baudrate to be unsigned.

Nothing is using this, so punt it from the gd. Seems to just be a copy
& paste wart from the initial port.

All the global flag defines are the same across all arches. So unify them
in one place, and add a simple way for arches to extend for their needs.

This field gets read in one place (by "bdinfo"), and we can replace
that with getenv("ipaddr"). After all, the bi_ip_addr field is kept
up-to-date implicitly with the value of the ipaddr env var.
