- Subject: Fix -findirect-dispatch Java failures on SPARC/Linux
The problem is
LIBGCJ_BC_SPEC="%{findirect-dispatch:-fPIC}"
but you cannot compile with -fPIC without assembling with -K PIC on the SPARC.
Hence the attached kludge, which yields:
Native configuration is sparc-unknown-linux-gnu
=== libjava tests ===
Running target unix
=== libjava Summary ===
# of expected passes 2574
Does anyone have a better idea?

* config/sparc/linux.h (ASM_SPEC): Pass -K PIC if -findirect-dispatch.
* config/sparc/linux64.h (ASM_SPEC): Likewise.
