You probably have some CFLAGS and LDFLAGS defined in the environment.
This way of passing CFLAGS and LDFLAGS to the autotools is deprecated.

No, these are unrelated problems. The problems you mention have been
solved by using the wrap-link.sh script, which you can seen on the
command line you posted, but which unfortunately either the CFLAGS or
LDFLAGS you pass, or your toolchain seem to upset.

To know if the issue is the flags or the toolchain, I ask you to
recompile with the same toolchain, but without your custom flags.
