[PATCH v1 0/4] Fix a series of problems caused by

[Lulu Cheng <chenglulu@loongson.cn>]

Because binutils2.42 corrects the implementation of
".align [abs-expr,[abs-expr[,abs-expr]]]".
The macro ASM_OUTPUT_ALIGN_WITH_NOP in GCC uses this assembler directive,
and an error occurs. See link below for detailed description.
https://gcc.gnu.org/pipermail/gcc-patches/2024-February/645067.html

In order to solve the above problems, do the following operations:

1. Delete macro definition ASM_OUTPUT_ALIGN_WITH_NOP. (cherry pick r14-4674)
2. Check whether binutils supports the relax function. (cherry pick r14-4160)
3. Disable relaxation if the assembler don't support
  conditional branch relaxation. (cherry pick r14-5434)

PR112299 is also fixed here.

Lulu Cheng (2):
  LoongArch: Delete macro definition ASM_OUTPUT_ALIGN_WITH_NOP.
  LoongArch: Check whether binutils supports the relax function. If
    supported, explicit relocs are turned off by default.

Xi Ruoyao (2):
  LoongArch: Disable relaxation if the assembler don't support
    conditional branch relaxation [PR112330]
  LoongArch: Define HAVE_AS_TLS to 0 if it's undefined [PR112299]
