Rollup merge of #82534 - nikic:musl-crtend, r=nagisa
Link crtbegin/crtend on musl to terminate .eh_frame For some targets, rustc uses a "CRT fallback", where it links CRT object files it ships instead of letting the host compiler link them. On musl, rustc currently links crt1, crti and crtn (provided by libc), but does not link crtbegin and crtend (provided by libgcc). In particular, crtend is responsible for terminating the .eh_frame section. Lack of terminator may result in segfaults during unwinding, as reported in #47551 and encountered by the LLVM 12 update in #81451. This patch links crtbegin and crtend for musl as well, following the table at the top of crt_objects.rs. r? ``@nagisa``
