 Default what Debian 32bit passes in addition to mesa options is:

/usr/lib/gcc/i586-linux-gnu/4.9/cc1 -E -quiet -v -imultiarch i386-linux-gnu -
-mtune=generic -march=i586

 That is with -mtune=generic -march=i586, with -mtune=native -march=native on
AMD Kabini it passes this:

 /usr/lib/gcc/i586-linux-gnu/4.9/cc1 -E -quiet -v -imultiarch i386-linux-gnu -
-march=btver2 -mmmx -mno-3dnow -msse -msse2 -msse3 -mssse3 -msse4a -mcx16
-msahf -mmovbe -maes -mno-sha -mpclmul -mpopcnt -mabm -mno-lwp -mno-fma
-mno-fma4 -mno-xop -mbmi -mno-bmi2 -mno-tbm -mavx -mno-avx2 -msse4.2 -msse4.1
-mlzcnt -mno-rtm -mno-hle -mno-rdrnd -mf16c -mno-fsgsbase -mno-rdseed -mprfchw
-mno-adx -mfxsr -mxsave -mxsaveopt -mno-avx512f -mno-avx512er -mno-avx512cd
-mno-avx512pf -mno-prefetchwt1 --param l1-cache-size=32 --param
l1-cache-line-size=64 --param l2-cache-size=2048 -mtune=btver2

 So Debian default works fine for the 10.2 branch, and for the 10.3-devel up to
the commit 37d43ebb28ce8be38f3d9b0805b8b14354ce786d . But anything newer is
affected, 10.3 branch and git master.

 Maybe some of those options need to be added to default, not sure what of
these make is work normal :)
