I have both `ldc` and `gdc` install on my OpenSUSE tumbleweed
machine.
Without `ldc-runtime-devel`, `gdc` is able to compile
successfully.
```bash
binary /usr/lib64/gcc/x86_64-suse-linux/13/d21
version v2.103.0-rc.1
predefs GNU D_Version2 LittleEndian GNU_DWARF2_Exceptions
GNU_StackGrowsDown GNU_InlineAsm D_LP64 assert D_PreConditions
D_PostConditions D_Invariants D_ModuleInfo D_Exceptions
D_TypeInfo all X86_64 D_HardFloat Posix linux CRuntime_Glibc
CppRuntime_Gcc
parse app
importall app
import
object (/usr/lib64/gcc/x86_64-suse-linux/13/include/d/object.d)
... rest omitted
```
However, after installing `ldc-runtime-devel`, gdc fails to
compile a "hello world" because it tries to use the phobos
library provided by ldc.
gdc installs its library at
`/usr/lib64/gcc/x86_64-suse-linux/13/include/d/`
ldc installs its library at `/usr/include/d`
`gdc -v source/app.d` shows,
```bash

How may I fix it? I tried to use "-I" and "-B" option, but to no
avail.
