LoongArch: When checking whether the assembler supports conditional branch relaxation, add compilation parameter "--fatal-warnings" to the assembler.
In binutils 2.40 and earlier versions, only a warning will be reported
when a relocation immediate value is out of bounds. As a result,
the value of the macro HAVE_AS_COND_BRANCH_RELAXATION will also be
defined as 1 when the assembler does not support conditional branch
relaxation. Therefore, add the compilation option "--fatal-warnings"
to avoid this problem.
gcc/ChangeLog:
* configure: Regenerate.
* configure.ac: Add parameter "--fatal-warnings" to assemble
when checking whether the assemble support conditional branch
relaxation.
