adding a new library to hotspot build

[Choe, Jiwon]

Hello,

I am adding code to OpenJDK 14 which uses a library that is currently not
part of the JDK build.
I put the .a library file in the directory where all other dependencies are
(/opt/sysroot/usr/lib/arm-linux-gnueabihf, since I am doing a
cross-compile), and I naively tried to add a reference to this library in
the build via "--with-extra-cflags" and "--with-extra-cxxflags" at the
configure stage, but I think the build is still failing to locate the
library.
What would be the proper way to add a new library to the build?

Thanks,
Jiwon
