Thank you for pointing out. I've switched to using Makefile. The
Makefile in the root directory has following content:
obj-m += module1/
obj-m += module2/
all:
$(MAKE) -C /home/lexa/linux M=$(PWD) O=$(PWD)/build_x86 modules
But the issue remain the same:
$ make
make -C /home/lexa/linux M=/home/lexa/module
O=/home/lexa/module/build_x86 modules
make[1]: Entering directory '/home/lexa/linux'
make[2]: Entering directory '/home/lexa/module/build_x86'
WARNING: Symbol version dump ./Module.symvers
is missing; modules will have no dependencies and modversions.

In case of external module build O= specifies a path to the kernel
build directory or the directory where I want the modules to be built?
