libtool: Limit a length of DLL name to 8.3 correctly
If a length of $release and/or $versionsuffix is more than 8 bytes,
a length of DLL name may be more than 8.
Then, this corrupts a generated DLL on OS/2.
This patch assures 3 bytes for libname, 2 bytes for release, and 3 bytes
for version at least.
* m4/libtool.m4 (soname_spec) [os2*]: Limit a length of DLL name to 8.3
correctly.
