Thanks, that's why I had two situations:

At work, I use an i386 system then the test "Check if we can use asm 
code" pass and build fail with:

output/host/usr/bin/i686-buildroot-linux-gnu-as _crc_i386.s
mv _crc_i386.o crc_i386.o
mv: mv _match.o match.o
cannot stat `_crc_i386.o': No such file or directory

At home, I use an x86_64 then the test fail thus there is no build error...

I have send a patch series to fix build issues with infozip package.

Best regards,
Romain Naour
