[PATCH] configure.ac: Also quote '$' in tbaseargs

[PATCH] configure.ac: Also quote '$' in tbaseargs

[Maciej W. Rozycki]

Hi,

 While working on some GDB changes I have stumbled across this, which 
looks like a buglet in the top-level configure.  Perhaps a three-way merge 
error from the past.  Unfortunately there is nothing in ChangeLog that 
would indicate when these bits were introduced.

 We have these two variables, $baseargs and $tbaseargs, that we handle 
almost identically, except some bits are omitted from $tbaseargs only, 
based on $skip_targ.  However, at the point we decide to quote '$' in any 
of the options collected we only do so for $baseargs.  As a result, '$' 
won't be escaped correctly in $tbaseargs and will break in sub-makes used 
for the target.  Have I missed anything?

 If not, then here's an obvious fix.  Found by inspection, I don't have a 
test case handy.  OK to apply?

Hi,

 Would anyone please have a look at:

http://gcc.gnu.org/ml/gcc-patches/2012-05/msg00044.html

I know this is trivial boring stuff, but perhaps especially because of 
this let's get rid of it ASAP?  Thanks.
