How to fix this error?

Command
(.venv) C:\Users\user1\zephyrproject\zephyr>west -v build -c -p auto -b native_posix samples\hello_world
Compiler:
C:\Program Files (x86)\mingw-w64\i686-8.1.0-posix-dwarf-rt_v6-rev0\mingw32\bin\gcc.exe
Environment variables:
ZEPHYR_BASE = C:\Users\user1\zephyrproject\zephyr
ZEPHYR_TOOLCHAIN_VARIANT = cross-compile
CROSS_COMPILE = C:\Program Files (x86)\mingw-w64\i686-8.1.0-posix-dwarf-rt_v6-rev0\mingw32\bin
CMAKE_CXX_COMPILER and CMAKE_C_COMPILER are set to C:\Program Files (x86)\mingw-w64\i686-8.1.0-posix-dwarf-rt_v6-rev0\mingw32\bin\gcc.exe

what should be ZEPHYR_TOOLCHAIN_VARIANT, it is set to "cross-compile" in environment variables but terminal logs shows "host". how the ZEPHYR_TOOLCHAIN_VARIANT is detected for native_posix target
