how does gcc pick the assembler, linker?

[kamaraju kusumanchi]

Can someone tell me how gcc picks it's assembler, linker? I am using
Sun Solaris 5.8.

For example, if I do

> gcc -print-prog-name=as
/usr/ccs/bin/as

> gcc -print-prog-name=ld
/usr/ccs/bin/ld

However, /usr/ccs/bin is not in the $PATH, $LD_LIBRARY_PATH.

I would like gcc to use as, ld located in some other directory. I want
this directory to be looked before it searches in /usr/ccs/bin etc.,
Any ideas on how to achieve it?
