Pass parameter to gcc linker

I need to pass parameter to gcc then cross build D code for ARM.
In my case I have some missversions (I think) in cross compile 
tool stack: sysroot builded with unknown (for me) compiler, I use 
compiler with exact glibc version but with other build flags, and 
may be something else.

Problem: then I try to build my D code I get this kinds of errors:

/arm-gcc/bin/../lib/gcc/arm-linux-gnueabihf/8.2.1/../../../../arm-linux-gnueabihf/bin/ error: /arm-gcc/bin/../libexec/gcc/arm-linux-gnueabihf/8.2.1/ not configured to support 64-bit little-endian object
/arm-gcc/bin/../lib/gcc/arm-linux-gnueabihf/8.2.1/../../../../arm-linux-gnueabihf/bin/ error: cannot find -lugin
/arm-gcc/bin/../lib/gcc/arm-linux-gnueabihf/8.2.1/../../../../arm-linux-gnueabihf/bin/ error: cannot find -lugin-opt=/arm-gcc/bin/../libexec/gcc/arm-linux-gnueabihf/8.2.1/lto-wrapper
/arm-gcc/bin/../lib/gcc/arm-linux-gnueabihf/8.2.1/../../../../arm-linux-gnueabihf/bin/ error: cannot find -lugin-opt=-fresolution=/tmp/cc89QFF3.res

I found only one resolution of problem: in ldc2.conf I select 
custom script for `-gcc` switch instead of direct compiler name

custom script disable lto for gcc call:

arm-linux-gnueabihf-gcc -fno-lto $@

how to pass `-fno-lto` to gcc without "custom-script-hacking"?
As I know ldc used gcc only for linkage, but `-L-fno-lto` don't 
has effect.

gcc from

ldc 1.22.0 from github
