The BSWAPxx() macros are now throwing the following warnings with
newer gcc versions. This is due to throwing an argument in that may
be evaluated more than one (I think) and therefore things like the
example below should be avoided.
Fix by making a set of BSWAPxx() wrappers which specifically only
evaluate 'x' once.
In file included lib/sbi/sbi_mpxy.c:21:
lib/sbi/sbi_mpxy.c: In function ‘sbi_mpxy_write_attrs’:
ib/sbi/sbi_mpxy.c:632:63: error: operation on ‘mem_idx’ may be undefined [-Werror=sequence-point]
632 | attr_val = le32_to_cpu(mem_ptr[mem_idx++]);

The shell script makes multiple call-outs to awk to get information
from the configuration file. It would be easier to just write the
whole thing in one .awk script and have the makefile altered to call
that instead.
There should be no functional difference other than the script type
and has been tested with PLATFORM=generic build. This should be both
quicker and easier to understand.

Send the errors to stderr, otherwise they end up being
written to the file the script was redirecting to in the
Makefile
Also, use EOF block to make it easier to redirect

If the script fails, we end up trying to build either
an empty or damaged .c file. Just remove it and let
gcc fail on non-existent file.
