[vkrawiec]

mold is a faster drop-in replacement for existing Unix linkers using highly parallelized algorithms
mold aims to enhance developer productivity by minimizing build time, particularly in rapid debug-edit-rebuild cycles
mold linker can be used with GCC since version 12 using argument -fuse-ld=mold
