gdb configured with --enable-shared --disable-static fails to link

[Dimitar Zhekov]

The version of GDB: 5.1.1
The type of machine you are using: i686-pc-linux-gnu
The operating system name and version number: rock-linux-1.5.12
What compiler (and its version) was used to compile GDB: gcc-2.95.3
How gdb was configured: ./configure --enable-shared --disable-static
What compiler (and its version) was used to compile the example program: N/A

When gdb is configured with --enable-shared --disable-static, only libbfd.so
and libopcodes.so are created, but not .a, yet the link is still attempted
against the (unexisting) libbfd.a and libopcodes.a, which fails, of course.
This can probably be easily fixed, as demonstrated by the following example:

which produces a valid shared executable on i386 systems. Being unfamiliar
with the GNU autoconf/automake system, I wasn't able to set LIBTOOL properly.
