When RPM_PACKAGE_RELEASE as an env variable, used by /usr/lib/rpm/redhat/redhat-package-notes contains a new line, compiling with  -specs=/usr/lib/rpm/redhat/redhat-package-notes as a linker option cases an internal compile error.

        : && /usr/bin/c++   CMakeFiles/cmTC_16a53.dir/src.cxx.o -o cmTC_16a53  -specs=/usr/lib/rpm/redhat/redhat-package-notes && :
        c++: internal compiler error: in execute, at gcc.cc:3260

$ g++ --version
g++ (GCC) 14.2.1 20240912 (Red Hat 14.2.1-3)

Reproducible: Always

Steps to Reproduce:
1.CMakeLists.txt file of

cmake_minimum_required(VERSION 3.10)
project(MyProject)
set(CMAKE_CXX_STANDARD 14)
set(CMAKE_CXX_STANDARD_REQUIRED True)

SET(ENV{RPM_PACKAGE_NAME}    MyExecutable)
SET(ENV{RPM_ARCH}            x86_64)
SET(ENV{RPM_PACKAGE_VERSION} 11.11.1)
EXECUTE_PROCESS(COMMAND rpm --eval "1%{?dist}" OUTPUT_VARIABLE RPM_PACKAGE_RELEASE_EXPANDED)

# To avoid ICE
# STRING(STRIP "${RPM_PACKAGE_RELEASE_EXPANDED}" RPM_PACKAGE_RELEASE_EXPANDED)

SET(ENV{RPM_PACKAGE_RELEASE} ${RPM_PACKAGE_RELEASE_EXPANDED})

EXECUTE_PROCESS(COMMAND "env" OUTPUT_VARIABLE ENV_IS_THIS ECHO_OUTPUT_VARIABLE)

include(CheckCXXSourceCompiles)
SET(CMAKE_REQUIRED_LIBRARIES -specs=/usr/lib/rpm/redhat/redhat-package-notes)
CHECK_CXX_SOURCE_COMPILES("int main(void) { return 0; }"  THIS_BREAKS)


2. cmake 
.
(appoligies for cmake example, shell attempts seem to be consuming the newline)
Actual Results:  
RPM_PACKAGE_NAME=MyExecutable
RPM_ARCH=x86_64
RPM_PACKAGE_VERSION=11.11.1
RPM_PACKAGE_RELEASE=1.fc41
