Bug#39739: unable to link after -fno-rtti automatically removed from c++ flags

[kalbun at inwind.it]

Package: kdevelop
Version: KDevelop 2.2.1 (using KDE 2.2.1 )
Severity: normal
Installed from:    Unspecified Linux
Compiler:          Not Specified
OS:                Linux
OS/Compiler notes: gcc 2.96 20000731

I recently downloaded Kdevelop 2.2.1 and noticed that even if you add the flag -fno-rtti in the compiler flags, it is automatically removed.
This results in the linker being unable to complete its job. 
I discovered the problem because an old project (generated with the previous KDevelop) was still linking perfecty.
The only solution was to add the flags to Makefile by hand (and to do so each time makefiles are regenerated).
