Revert "Merge pull request #86954 from lovesegfault/binutils-2.34"

Pythons find_library is broken with binutils 2.34, and numpy could not import libraries because of not properly aligned ELF's.

This is the second time binutils 2.34 got reverted. Next time, we should have a dedicated Hydra job for it.

This reverts commit 629fa8a2d459449eeb3f7c911b765e58ac830254, reversing
changes made to 4ddd080d1978b821391ad099806c18ac6a654e41.

+Subject: [PATCH] x86: Add a GNU_PROPERTY_X86_ISA_1_USED note if needed
+
+When -z separate-code, which is enabled by default for Linux/x86, is
+used to create executable, ld won't place any data in the code-only
+PT_LOAD segment.  If there are no data sections placed before the
+code-only PT_LOAD segment, the program headers won't be mapped into
+any PT_LOAD segment.  When the executable tries to access it (based
+on the program header address passed in AT_PHDR), it will lead to
+segfault.  This patch inserts a GNU_PROPERTY_X86_ISA_1_USED note if
+there may be no data sections before the text section so that the
+first PT_LOAD segment won't be code-only and will contain the program
+header.
+
+Testcases are adjusted to either pass "-z noseparate-code" to ld or
+discard the .note.gnu.property section.  A Linux/x86 run-time test is
+added.
+
+bfd/
+
+	PR ld/23428
+	* elfxx-x86.c (_bfd_x86_elf_link_setup_gnu_properties): If the
+	separate code program header is needed, make sure that the first
+	read-only PT_LOAD segment has no code by adding a
+	GNU_PROPERTY_X86_ISA_1_USED note.

+Subject: [PATCH] x86: Properly add X86_ISA_1_NEEDED property
+
+Existing properties may be removed during property merging.  We avoid
+adding X86_ISA_1_NEEDED property only if existing properties won't be
+removed.
+
+bfd/
+
+	PR ld/23428
+	* elfxx-x86.c (_bfd_x86_elf_link_setup_gnu_properties): Don't
+	add X86_ISA_1_NEEDED property only if existing properties won't
+	be removed.
+
+ld/
+
+	PR ld/23428
+	* testsuite/ld-elf/dummy.s: New file.
+	* testsuite/ld-elf/linux-x86.S: Add X86_FEATURE_1_AND property.
+	* testsuite/ld-elf/linux-x86.exp: Add dummy.s to pr23428.

+Subject: [PATCH] x86: Properly merge GNU_PROPERTY_X86_ISA_1_USED
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Without the GNU_PROPERTY_X86_ISA_1_USED property, all ISAs may be used.
+If a bit in the GNU_PROPERTY_X86_ISA_1_USED property is unset, the
+corresponding x86 instruction set isn’t used.  When merging properties
+from 2 input files and one input file doesn't have the
+GNU_PROPERTY_X86_ISA_1_USED property, the output file shouldn't have
+it neither.  This patch removes the GNU_PROPERTY_X86_ISA_1_USED
+property if an input file doesn't have it.
+
+This patch replaces the GNU_PROPERTY_X86_ISA_1_USED property with the
+GNU_PROPERTY_X86_ISA_1_NEEDED property which is the minimum ISA
+requirement.
+

+

+	GNU_PROPERTY_X86_ISA_1_USED if an input file doesn't have it.
+	(_bfd_x86_elf_link_setup_gnu_properties): Adding the
