Now I have another issue during make:

checking for RTEMS_CPU_MODEL...
checking for RTEMS_BSP_FAMILY... riscv_generic
checking for CPU_CFLAGS... (cached) -m32 -march=I
checking for CFLAGS_OPTIMIZE_V... (cached) -O0 -g
checking for style of include used by make... GNU
checking for riscv32-rtems4.12-gcc... riscv32-rtems4.12-gcc
checking for riscv32-rtems4.12-gcc... (cached) riscv32-rtems4.12-gcc
checking whether the C compiler works... no
configure: error: in
`/home/reprofy/Projects/riscv/rtems/development/rtems/kernel/riscv32/riscv32-rtems4.12/c/riscv_generic':
configure: error: C compiler cannot create executables

Now I can see the error - there is no such an option "-m32" in 32-bit gcc.
But what does "(cached)" mean?
