WINDOWS-BASED TOOLCHAIN BUILD

```
Description: Windows build issue. Some of the configurations that use NXFLAT have
the linker script specified like this:

NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1) -T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-gotoff.ld -no-check-sections

That will not work for windows-based tools because they require Windows
style paths. The solution is to do something like this:

if ($(CONFIG_CYGWIN_WINTOOL),y)
NXFLATLDSCRIPT=${cygpath -w $(TOPDIR)/binfmt/libnxflat/gnu-nxflat-gotoff.ld}
else
NXFLATLDSCRIPT=$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-gotoff.ld
endif

Then use

NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1) -T"$(NXFLATLDSCRIPT)" -no-check-sections

Status: Open
Priority: There are too many references like the above. They will have
to get fixed as needed for Windows native tool builds.
