1  autosetup-find-tclsh: Quote CC_FOR_BUILD to prevent word splitting
 2  
 3  In some build environments, CC_FOR_BUILD can include essential compiler
 4  flags. For example, in Guix it may have a value such as:
 5  `/gnu/store/10krix03rl5hqjv2c0qmj44ic9bgd8rc-gcc-toolchain-13.3.0/bin/gcc -isystem /gnu/store/10krix03rl5hqjv2c0qmj44ic9bgd8rc-gcc-toolchain-13.3.0/include`
