x86_64 build on Windows

[ThibautRousselet]

Hello!

I managed to build bgfx on arm/arm64 and x86 Android from Windows using Genie.
However I did not manage to build for x86_64 i get the Following error :

D:\EngineTests\bgfx-android\bgfx>make android-x86_64 
make -R -C .build/projects/gmake-android-x86 config=debug64 
make[1]: entrant dans le répertoire « D:/EngineTests/bgfx-android/bgfx/.build/projects/gmake-android-x86 » 
"==== Building bx (debug64) ====" 
allocator.cpp 
error: unknown target CPU 'i686'

Here is what the command is doing (the same as make android-x86 but with config=release64/debug64):

.build/projects/gmake-android-x86:
android-x86_64-debug: .build/projects/gmake-android-x86 ## Build - Android x86_64 Debug and Release
	$(MAKE) -R -C .build/projects/gmake-android-x86 config=debug64
android-x86_64-release: .build/projects/gmake-android-x86 ## Build - Android x86_64 Debug and Release
	$(MAKE) -R -C .build/projects/gmake-android-x86 config=release64
android-x86_64: android-x86_64-debug android-x86_64-release ## Build - Android x86_64 Debug and Release

I am probably missing an option or a environment variable maybe, but I have not found it yet does anyone has an idea please?
