[PATCH] LoongArch: fix MUSL_DYNAMIC_LINKER

[PATCH] LoongArch: fix MUSL_DYNAMIC_LINKER

[Peng Fan]

The system based on musl has no '/lib64', so change it.

gcc/
	* config/loongarch/gnu-user.h (MUSL_DYNAMIC_LINKER): Redefine.

I like the change.  IMO Glibc-based systems should avoid /lib64 as well
but it's too late to change it now.

Could you provide a link to the Musl doc as a reference?  I'd like to
include the link in the commit message.

Yes, https://wiki.musl-libc.org/guidelines-for-distributions.html, "Multilib/multi-arch" section of this
introduces it.
