libpayload: Implement gcc wrappers for libpayload
libpayload uses a ton of flags and other scary gcc and ld options. These wrappers hide most of that from the user, so that using libpayload is as easy as lpgcc -o hello hello.c Signed-off-by: Jordan Crouse <jordan.crouse@amd.com> Acked-by: Uwe Hermann <uwe@hermann-uwe.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@3226 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
