Subject: [Patch 1/1] BaseTools tools_def.template: Add GCC link script in X86 ASLDLINK_FLAGS

This fix refers to commit 14ca435fb6c059eaeb7fe6eedbe4738ffaf336d0.
GCC link script is used to discard the unused section data from ELF image.
ASLDLINK_FLAGS requires it to remove the unnecessary section data, then GenFw can be used to retrieve the correct data section from ELF image.
