The lack of link source de-duplication causes AddressSanitizer to complain ODR violations, and makes GNU ld abort when combined with clang's LTO. Previously, the non-standard prefix was necessary for fork-fuzzing. Meson wraps all standard-prefixed libraries with --start-group and --end-group. This made a fork-fuzz.ld linker script wrapped as well and broke builds. Commit d2e6f9272d33 ("fuzz: remove fork-fuzzing scaffolding") dropped fork-fuzzing so we can now restore the standard prefix. The occurences of the prefix were detected and removed by performing a tree-wide search with 'fa' and .fa (note the quotes and dot).
