as aclocal-1.16 may not be available on the build host as make has no
dependancies. remove patch to configure.ac. patch still works as the
required depends are still available.
Packages referencing variables defined in setup_toolchain such as CC, CXX,
AR, CFLAGS, LDFLAGS, HOST_CC etc. etc. must only reference these variables in
pre_build()/pre_configure()/pre_make() etc. functions, as the variables will not
be available when the package is sourced, but will be available after the call
to setup_toolchain() from scripts/build.
This reverts commit e0b6641f50.
Changing configure.ac requires aclocal-1.15 to be installed on the
build host as the configure script needs to be regenerated.
This breaks builds on all systems without automake-1.15, so revert
the change until a solution for the Arch make issue is found
that doesn't introduce a ton of host dependencies.
