tests/lib/csu, tests/libexec/ld.elf_so: Apply CTFMERGE=: workaround.

The workaround for

PR toolchain/59364: ctf tools needs update

required an update after fixing

PR toolchain/57241: mips64el--netbsd-install core dumps randomly

by splitting the recipes for ${PROG} and ${PROG}.debug into an
intermediate ${PROG}.link to avoid overwriting ${PROG} inside the
recipe for ${PROG}.debug.

This is kludgey (writing the `.link' suffix into a Makefile isn't
great) but I see only two cases of it so this'll do for now.

tests/lib/csu/Makefile: Use PROGS_CXX, not PROG_CXX.

There are multiple programs here.

Should fix:

nbmake: /home/riastradh/netbsd/current/src/share/mk/bsd.prog.mk:624: warning: Invalid character " " in variable name "OBJS.h_initfini1 h_initfini2 h_initfini3"

centralize pack-relative-relocs handling

Fix the clang build which complains about pack-relative-relocs ignored.

lib/csu: Test a static PIE with RELR relocations.

PR bin/59360: ld.elf_so(8): missing RELR support

tests/lib/csu: Build h_hello.o with -fPIE, not -fpie.

Static libraries like libc may overflow the bounds assumed by -fpie.
Resolves:

h_hello.o: in function `main':
h_hello.c:(.text.startup+0x30): relocation truncated to fit: R_SPARC_GOT13 against symbol `__sF' defined in .data.rel section in /tmp/build/2025.04.27.10.22.23-sparc64/destdir/usr/lib/libc.a(findfp.o)

lib/csu: Add tests of {static, dynamic} x {pie, non-pie}.

Main goal here is to test static pies, but let's take advantage of
this to test the same code several ways, since the csu logic has some
differences for static vs dynamic builds too like the ordering of
_libc_init calls.

PR lib/59359: static pies are broken

branches: 1.7.12;
Add an initfini_array test that does not depend on the linker putting it
there automatically.

branches: 1.6.2;
Add ifunc support for statically linked applications on x86, ppc, sparc
and ARM.

branches: 1.5.14;
Replace LDADD with LDSTATIC.

Whitespace.

Test alignment of constructor / destructor calls as well as the stack
of new threads. Currently implement for i386 and AMD64.

Replace csu test case with a C++ based version. This makes the various
assembler routines obsolete. Be more exhaustive by testing dynamically
linked, statically linked and dynamically loaded.

XXX currently hard-codes /usr/tests due to limitations of bsd.test.mk

Convert the csu tests to atf.
