From: =?UTF-8?q?=C4=B0smail=20D=C3=B6nmez?= <redacted> This is the first step for enabling ASLR (Address Space Layout Randomization) support. We want to enable ASLR for better protection against exploiting security holes in Git: it makes it harder to attack software by making code addresses unpredictable. The problem fixed by this commit is that `ld.exe` seems to be stripping relocations which in turn will break ASLR support. We just make sure it's not stripping the main executable entry.
