#### Steps to reproduce the issue

I did following changes in library_generation.sh
1、change arm-none-eabi-gcc to rx-elf-gcc
in libmicroros.mk
1、change
X_CC := arm-none-eabi-gcc
X_CXX := arm-none-eabi-g++
into
X_CC := rx-elf-gcc
X_CXX := rx-elf-g++
#### Expected behavior
generate a microros library for RX26T

#### Actual behavior
build error

#### Additional information

Start with library_generation.sh, libmicroros.mk, and toolchain.cmake.in, then rerun the library_generation.sh command shown in the report using the RX26T toolchain. Investigate the reported build failure and verify that the process completes and generates a micro-ROS library for RX26T.
