Libraries linked to the lld elf library exposes a function named main. When debugging code linked to such libraries and intending to set a breakpoint at main, the debugger also sets breakpoint at the main function at lld elf driver. The possible choice was to rename it to link but that would again clash with lld::*::link. This patch tries to consistently rename them to linkerMain.
