Makefile: Use -fno-strict-aliasing globally

The -fstrict-aliasing option is implicitly enabled at levels -O2,
-O3, -Os by GCC. This option allows the compiler to assume the
strictest aliasing rules applicable to the language being compiled.
For example, the practice of reading from a different union member
than the one most recently written to (called "type-punning") is
common. In this case, "type-punning" only works if the memory is
accessed through the union type, but might not work by taking the
address, casting the resulting pointer and dereferencing the result,
which is an undefined behavior per the "strict aliasing rules".

GCC's -Wstrict-aliasing (included in -Wall) option does not catch
all cases, but does attempt to catch the more common pitfalls. So
there are cases that GCC does not report but the codes are violating
the "strict aliasing rules".

Given lots of codes that may be written to rely on "type-punning",
and Linux kernel disables it by -fno-strict-aliasing globally, since
U-Boot currently does this on nds32/riscv/x86 builds only, extend
this for all architecture builds.

The only straight forward fix that doesn't involve nasty hacks I

At present map_sysmem() maps an address into the sandbox RAM buffer,
return a pointer, while map_to_sysmem() goes the other way.

The mapping is currently just 1:1 since a case was not found where a more
flexible mapping was needed. PCI does have a separate and more complex
mapping, but uses its own mechanism.

However this arrange cannot handle one important case, which is where a
test declares a stack variable and passes a pointer to it into a U-Boot
function which uses map_to_sysmem() to turn it into a address. Since the
pointer is not inside emulated DRAM, this will fail.

Add a mapping feature which can handle any such pointer, mapping it to a
simple tag value which can be passed around in U-Boot as an address.
