Compilation fails with the new gcc-rx compiler version 14.2.0

[sayyadumar]

The following is my setup:

sayyad@sayyad-tux:~/projects/rx/RX$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 24.04.2 LTS
Release:        24.04
Codename:       noble

sayyad@sayyad-tux:~/projects/rx/RX$ rx-elf-gcc --version

When i try to compile with the ./all_project_build.sh -debug , I get the following errors,

sayyad@sayyad-tux:~/projects/rx/RX$ ./all_project_build.sh -debug

      |                         ^~~~~~~~~~

This error can be fixed by defining the missing function, which i did. But after fixing that i get further errors,

This looks like a libc error, so i thought passing the -specs=nano.specs would help, but this complains about missing _sbrk function.

Could you please take a look? If you want i can help too.
