ARM build issues

[1ndahous3]

There are several issues when building on an ARM7 system (armhf) without the SSE2 instruction set.

1. Wrap all (2) #include <xmmintrin.h> in #ifdef UI_SSE2 macro:

luigi.h:18:10: fatal error: xmmintrin.h: No such file or directory
   18 | #include <xmmintrin.h>
      |          ^~~~~~~~~~~~~

2. Dynamic detection of SSE2 support in build.sh to define UI_SSE2 macro.
3. Wrap all _mm* functions in #ifdef UI_SSE2 macro, write #else blocks:
   

   gf/luigi.h

   Lines 930 to 934 in f6694e2

   	float _UISquareRootFloat(float x) {
   	float result[4];
   	_mm_storeu_ps(result, _mm_sqrt_ps(_mm_set_ps(0, 0, 0, x)));
   	return result[0];
   	}

luigi.h: In function ‘float _UISquareRootFloat(float)’:
luigi.h:936:36: error: ‘_mm_set_ps’ was not declared in this scope
  936 |  _mm_storeu_ps(result, _mm_sqrt_ps(_mm_set_ps(0, 0, 0, x)));
      |                                    ^~~~~~~~~~
luigi.h:936:24: error: ‘_mm_sqrt_ps’ was not declared in this scope
  936 |  _mm_storeu_ps(result, _mm_sqrt_ps(_mm_set_ps(0, 0, 0, x)));

  936 |  _mm_storeu_ps(result, _mm_sqrt_ps(_mm_set_ps(0, 0, 0, x)));
      |  ^~~~~~~~~~~~~

4. Other errors and warnings:

Is this fixed in ca7e4c5?

Is this fixed in ca7e4c5?

All fixed except for the count type convert error in the XGetWindowProperty() call.

[1ndahous3]

And the question is, can it now be compiled with a color picker without SSE2?

Now fixed in 20cb042.

Not yet. But gf does not use the color picker, so it is not an issue. I will make the color picker work without SSE2 before merging it into the luigi library repository, though.

Now it happens with the next variable bytesLeft :D
I fixed the type locally and the debugger finally compiled.
