This doesn't work as intended.
Given e.g. --cross-cc-aarch64=aarch64-linux-gcc
+ cc_arch=aarch64=aarch64-linux-gcc
+ eval 'cross_cc_aarch64=aarch64-linux-gcc=$optarg'
++ cross_cc_aarch64=aarch64-linux-gcc=aarch64-linux-gcc
Which sets the variable "cross_cc_aarch64"
to "aarch64-linux-gcc=aarch64-linux-gcc".
Which of course won't exist to execute.
