This appears to be another case where the hotspot and jdk repo makefiles differ.
hotspot does:
# statically link libgcc and/or libgcc_s, libgcc does not exist before gcc-3.x.
ifneq ("${CC_VER_MAJOR}", "2")
STATIC_LIBGCC += -static-libgcc
endif
making it look like the jdk repo makefile is in error.
I continue to be surprised that with all the strange fiddling with
linker flags (use of -static-libgcc is not encouraged), that jdk
binaries have such a high degree of binary compatibility.
