When I use the package to compile my arm none binary, I get:

/usr/lib64/gcc/arm-none-eabi/13/ld:
/usr/lib64/gcc/arm-none-eabi/13/../../../../arm-none-eabi/lib/thumb/v8-m.main+fp/hard/libg.a(libc_a-syscalls.o):
in function `_close':
/home/abuild/rpmbuild/BUILD/newlib-4.3.0.20230120/build-regular-dir/arm-none-eabi/thumb/v8-m.main+fp/hard/newlib/../../../../../../newlib/libc/sys/arm/syscalls.c:443:
multiple definition of `_close';
CMakeFiles/main.dir/main/system_calls.c.obj:<snip>200/main/system_calls_override.c:28:
first defined here


I have done some searching but as fare I understand this Unix functions should
not be included in this newlib variant.

Reproducible: Always

Steps to Reproduce:
1.run make dev #with cross-arm-none-newlib-devel and cross-arm-none-gcc13
installed

Results are output of a reduced project and also got:
/usr/lib64/gcc/arm-none-eabi/13/ld: warning: cannot find entry symbol
Reset_Handler; defaulting to 08020000
Warning that can be ignored 

I can supply a tarball of the reduced project
