Seems that the problem comes from the order of the library paths. The order is the next: -L/lib64 -L/usr/lib -L/usr/lib/gcc/x86_64-pc-linux-gnu/11.2.1 -L/usr/lib64 -L/usr/x86_64-pc-linux-gnu/lib 

bfd it finds the 32 bit version of the libraries and prints a warning (eg: "skipping incompatible /usr/lib/libm.a when searching for -lm"), but lld directly prints an error. Moving /usr/lib64 before /usr/lib solves this issue, although I don't know how to accomplish that with econf.
