2.46.0 does not build on OSX

Just for the sake of tracking this issue. I get the following compile error:

libtool: link: gcc -dynamiclib  -o .libs/librsvg-2.2.dylib  librsvg/.libs/2_la-librsvg-features.o librsvg/.libs/2_la-rsvg-base.o librsvg/.libs/2_la-rsvg-handle.o librsvg/.libs/2_la-rsvg-pixbuf.o   -Wl,-force_load,./.libs/librsvg_c_api.a  -L/Users/jenkins/DCV_JHBUILD/inst/lib -lpng16 -lz -lcairo-gobject -lgdk_pixbuf-2.0 -lgio-2.0 -lpangocairo-1.0 -lcairo -lpangoft2-1.0 -lpango-1.0 -lgobject-2.0 -lharfbuzz -lfontconfig -lfreetype -lcroco-0.6 -lintl -lglib-2.0 -lxml2  -g -O2 -fstack-protector-strong -Wl,-headerpad_max_install_names   -install_name  /Users/jenkins/DCV_JHBUILD/inst/lib/librsvg-2.2.dylib -compatibility_version 49 -current_version 49.0 -Wl,-single_module -Wl,-exported_symbols_list,.libs/librsvg-2-symbols.expsym

2.44.13 seems to build without issues.
