It seems that the linking flag "-target mips-linux-gnu" was removed by
libtool which resulted in the linker (clang) assuming the wrong
architecture (x86_64). The flag was set in the LDFLAGS environment

Libtool only passes through options that it understands. Otherwise one must use -Wc, and -Wl, syntax to pass options to the compiler or linker.

Also, usually cross-tools are supposed to be named a particular way (including the target triplet in the name) according to autoconf conventions (see the autoconf documentation). This helps autoconf and libtool understand that cross-compilation is being performed, and assures that the correct tools are used.

On a system here, I see cross tools named like mips-linux-gcc and mips-unknown-linux-uclibc-gcc.
