Summary: [bisected commit 883987] crosscompiling fails with
util/u_cpu_detect.c:247:4: error: 'asm' undeclared
(first use in this function)
Severity: normal

Commit 883987503fc79691398eb024f37480ff083805a3 breaks crosscompilation when
building with the following:
baseExec="./autogen.sh --prefix=/usr \
--enable-debug \
--enable-osmesa \
--enable-gbm \
--enable-xvmc \
--enable-vdpau \
--enable-gles1 \
--enable-gles2 \
--enable-openvg \
--enable-xorg \
--enable-xa \
--enable-egl \
--enable-gallium-egl \
--enable-glx-tls \
--enable-texture-float \
--enable-wgl \
--with-gallium-drivers=r600,swrast,svga \
--with-dri-drivers= \
--with-egl-platforms=x11,drm,wayland"
export CFLAGS='-m32'
export CXXFLAGS='-m32'
export LLVM_CONFIG='/usr/bin/llvm-config32'
export PKG_CONFIG_PATH="/usr/lib/i386-linux-gnu/pkgconfig"
Exec32="$baseExec --enable-32-bit --build=x86_64-pc-linux-gnu
--host=i686-pc-linux-gnu --libdir=/usr/lib/i386-linux-gnu
--includedir=/usr/include/i386-linux-gnu"
$Exec32

It fails with:
CC util/u_cpu_detect.lo
util/u_cpu_detect.c: In function 'sse2_has_daz':
util/u_cpu_detect.c:247:4: error: 'asm' undeclared (first use in this function)
asm volatile ("fxsave %0" :: "m" (fxarea));
^
util/u_cpu_detect.c:247:4: note: each undeclared identifier is reported only
once for each function it appears in
util/u_cpu_detect.c:247:8: error: expected ';' before 'volatile'

However, compiling normally for my 64bit architecture works fine.
Bad commit 883987503fc79691398eb024f37480ff083805a3
util: try much harder to set DAZ flag
