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.

Changes for v3: - use -undef instead of ansi. With -undef, there is no need to modify iot2050.env and smegw01.env files anymore.
Changes for v2: - explain the change of iot2050.env and smegw01.env in the commit log
