Created attachment 569070 [details] The result of 'emerge --info' in my system.
For some reason, Qt is trying to use AES CPU instructions, but your CPU doesn't support that. Could you please attach output of 'emerge --info' and 'cat /proc/cpuinfo'?
Created attachment 571130 [details] cat /proc/cpuinfo
According to your emerge --info, you are using in your CFLAGS: -march=sandybridge. Per the GCC docs[1], this implies that your CPU supports the AES instruction set. However, according to your /proc/cpuinfo, your CPU does not support the AES instruction set. Please try again with correct CFLAGS (-march=native is recommended for most cases). 1: https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html#x86-Options
