hsdis binary is expected to be provided in CompoundVM

[luchsh]

The hsdis library is useful for diagnosing and debugging.
But it would be a little complex to setup a workable environment to build a compatible binary libhsdis.so. (see https://www.morling.dev/blog/building-hsdis-for-openjdk-15/)

In the private repository at ByteDance there is some special place to hold the binaries of hsdis; but when we decided to opensource this project, below lines got commented out:

CompoundVM/cvm.mk

Line 142 in c777c7d

#cp -f $(WORKSPACE)/bin/linux-$(CVM_ARCH)/hsdis-$(ARCH_DIR).so $$(dirname $$(find $@ -name libjava.so))

CompoundVM/cvm.mk

Line 146 in c777c7d

#cp -f $(WORKSPACE)/bin/linux-$(CVM_ARCH)/hsdis-$(ARCH_DIR).so $$(dirname $$(find $@ -name libjava.so))

and this ought to be fixed :)

相比openjdk使用的libhsdis.so，CVM使用的libhsdis.so是需要额外的处理吗。

libhsdis.so构建方式如下：

wget https://ftp.gnu.org/gnu/binutils/binutils-2.46.1.tar.xz
tar xf binutils-2.46.1.tar.xz
cd jdk
bash configure --with-hsdis=binutils --with-binutils-src=../binutils-2.46.1
make build-hsdis

result:

ls -lh build/linux-x86_64-server-release/support/hsdis/libhsdis.so
-rwxrwxr-x 1 yansendao yansendao 2.3M Jul 14 11:00 build/linux-x86_64-server-release/support/hsdis/libhsdis.so

不需要额外处理，cvm 和 libhsdis.so 应该是兼容的
