Compile: Add feature to continue where installation process left off after failure

[ghost]

It would be nice to have the option to tell Compile to continue the installation a package after it has been built successfully. Too many times a package like Glibc has too many file exists errors due to symlink conflicts from its previous installation. It like playing a game of Cat and Mouse where each time a silly failure like that occurs, I have to manually remove the symlink and rebuild again, hoping it will succeed the next time until it actually does. I have to rebuild Glibc over 10 times now because of this.
