gcc 2.96: A configure fix to replace "$(...)" with "${...}"

[Maciej W. Rozycki]

Hello,

 I believe it's gcc that maintains the master copy of the toplevel
configure script hence I am sending the following patch here.

 There are two places in the script a "$(...)" type variable references
are used.  While for make they are interchangeable with "${...}" type
references, for the shell their meanings differ.  Actually the latter type
is interchangeable between these two programs and is used elsewhere as
well as within configure scripts generated by autoconf.

 The following patch allows constructs such as `./configure
--libdir='${exec_prefix}'/<path>' work as expected.  The patch was
generated from the binutils tree but it applies cleanly against gcc 2.96
as of May 1st. 

  Maciej
