INSTALL=../ problem

[Jeff Johnston]

I have checked in a patch for the INSTALL=../ problem.  I was trying to 
build newlib under Eclipse and was noticing that install failed 
everytime due to INSTALL being set to ../

After some experimentation I found that a magic configure variable was 
getting set too early (set to empty) and was later put into a case 
statement to see if the path was relative or absolute.  The relative 
case was defaulted and ../ was added.  If newlib bothered to cache the 
ac_cv_path_install variable, then everything worked out fine at install 
time other than the fact that the INSTALL variable was set incorrectly. 
  Outside of Eclipse in my build directory, this was the case.  When it 
doesn't get cached, errors result.

Anyway, with the hack I added, the install path is correct and I can 
build under Eclipse now.
