It appears to mostly work:

[lib64]$ file libstdc++.so.6.0.20
libstdc++.so.6.0.20: ELF 64-bit LSB shared object, x86-64, version 1
(SYSV), dynamically linked, stripped

[lib64]$ file * | grep '\.so' | grep not
libgcc_s.so.1:              ELF 64-bit LSB shared object, x86-64,
version 1 (SYSV), dynamically linked, not stripped


Of all SO's built by GCC, only libgcc_s.so.1 is not stripped.  Not sure
why.

I tried to manually strip it but I'm not sure it's working:

[lib64]$ file libgcc_s.so.1
libgcc_s.so.1: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV),
dynamically linked, not stripped

[lib64]$ objcopy --strip-debug libgcc_s.so.1

[lib64]$ file libgcc_s.so.1
libgcc_s.so.1: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV),
dynamically linked, not stripped


Incidentally, I noticed that other open source libraries (libxml2,
libxml++ to name 2) also have this "make install-strip" target.  I
suspect it's generated by autoconf and/or friends.  I verified that
using it generates stripped SO's.
