Regression from 1.5.0 in compiling SBCL on Haiku

Currently, ABCL is the only way to run Common Lisp on Haiku (https://www.haiku-os.org/). I try to bootstrap SBCL on Haiku usinbg ABCL. Previously, bootstrap (first stage of compilation) was possible with ABCL 1.5.0. Now with ABCL 1.6.0 the compilation fails with the attached Java error. This is a regression fomr 1.5.0.
