bd38ba4b6b GNU ar warning about deterministic mode
GNU ar currently produces the following string of warnings:
Warning: Archive 'libefi.a' seems to have been created in
deterministic mode.
'<file>.o' will always be updated. Please consider passing
the U flag to ar to avoid the problem. This patch fixes the issue.

b2c4db065f I did a quick review of the MS x86_64 calling convention for floating
point and as far as I can tell it agrees with the UEFI spec.
The attached patch removes -mno-mmx and -mno-sse for x86_64 and adds
a new Print target, "%f", to print float and double types.

It seems to compile for ia32, although I'm not sure why - shouldn't
it be throwing errors because the new function FloatToStr() in print.c
accepts a float, yet I left -no-sse for ARCH=ia32? A better solution
might be to add -msoft-float for targets where the floating point
calling convention doesn't match the UEFI spec. As I'm not familiar
with UEFI on ia32, I didn't make any changes to it.

50b883773f -fpic is not needed for MinGW, and MinGW32 issues a warning as a
result, which breaks gnu-efi compilation due to -Werror:
gnu-efi/lib/boxdraw.c:1:0: error: -fpic ignored for target
(all code is position independent) [-Werror]

This patch ensures that -fpic is disabled when MinGW is used.

a213b514a3 Note that there are probably some bugs on some architectures that
I havan't fixed, so somebody will see a build failure from this.
It will most likely be very easy to fix.

11a459ba96 This patch makes the following symbols (relatively) consistent between
all of our linker scripts:

_text
_etext
_text_size
_data
_edata
_data_size

There are various things that are slightly different (positions of
.rela*, .dynamic, and similar in relation to .data), but _text and _data
are now always at the beginning of their respective sections with regard
to how a debuger would reference the debug info, and _etext and _edata
are now always extant and guaranteed to be after any of the respective
kind of data the debugger would look for in that section.

This also adds an application example of how it might be used, and a
makefile target for %.efi.debug which will generate a separate debuginfo
file for that example.

This also enables debugging by default (i.e. -g is in CFLAGS) and adds
.note.gnu.build-id sections to our .so files (i.e. --build-id=sha1 is in
LDFLAGS).

ce7098fb52 Enable out-of-tree building
This patch enables building gnu-efi outside of the source tree.
That in turn enables building for multiple architectures in parallel.

The build directory is controlled by the OBJDIR make variable.  It
defaults to the value of ARCH, and can be overridden from the command
line.

This patch also cleans up some doubled slashes between INSTALLROOT
and PREFIX.

530d68ba19 The gnu-efi-3.0 toplevel subdirectory is really annoying. Kill it.
