Why arm-linux-gnueabi-gcc cannot compile even simple test file? - linux

Question

I installed cross-compilation tools on my Ubuntu system using:
sudo apt-get install gcc-arm-linux-gnueabi binutils-arm-linux-gnueabi
And then i made simple .c file which compiles ok, but when gcc runs assembler stage, it is for unknown reason invokes 'as' command, instead of appropriate 'arm-linux-gnueabi-as' command and as result compilation fails with following errors:
arm-linux-gnueabi-gcc -v test.c
Using built-in specs.

GNU assembler version 2.28 (x86_64-linux-gnu) using BFD version (GNU Binutils for Ubuntu) 2.28
Assembler messages:
Fatal error: invalid -march= option: `armv5t'
As you can see, it fails, because it invoking wrong command - as, which knows only about x86_64-linux-gnu target, and does not recognizing armv5t architecture option.
How to force gcc toolchain to use correct cross-platform assembler/linker to produce binary, instead of 'as' 'ld' etc?
Is there something in my environment, that causing such behavior?
P.S. On my college's machine, installing same toolchain works without problem, however he has Ubuntu 16.04, while mine are 17.04..
And GCC executing following command for assembler:
/usr/lib/gcc-cross/arm-linux-gnueabi/5/../../../../arm-linux-gnueabi/bin/as
-v -march=armv5t -mfloat-abi=soft -meabi=5 -o /tmp/ccXru9b3.o /tmp/ccUwNPuq.s
As you can see, it takes right assembler and all is ok.. but not on my system..
