[Arm-dev] java-1.8.0 not building on armv5

Hi Fabian,

I fail to build java-1.8.0-openjdk on armv5.

I get errors regarding gdb:

+ gdb -q
/builddir/build/BUILD/java-1.8.0-openjdk-1.8.0.141-2.b16.el7.arm/openjdk/build/jdk8.build/images/j2sdk-image/bin/java
+ tee gdb.out

This is all related to a new section about gdb in the SPEC-file:

# Make sure gdb can do a backtrace based on line numbers on libjvm.so
gdb -q "$JAVA_HOME/bin/java" <<EOF | tee gdb.out
handle SIGSEGV pass nostop noprint
handle SIGILL pass nostop noprint
set breakpoint pending on
break javaCalls.cpp:1
commands 1
backtrace
quit
end
run -version
EOF
grep 'JavaCallWrapper::JavaCallWrapper' gdb.out


Now my question, does this build on armv7 ?
