Makefile: pass -undef option to cmd_gen_envp

Without the '-undef' option, the 'linux' string in .env files is
replaced with the string '1 '.
For example, in the board/armadeus/opos6uldev/opos6uldev.env file,

kernelimg=opos6ul-linux.bin

becomes

kernelimg=opos6ul-1 .bin

in the include/generated/env.in file.

That's because 'linux' is a System-specific Predefined Macros. [1]

Pass the '-undef' option to fix this issue.
