I upgrade from gcc 4.1.2 to 4.4.3 and discovered that the gcc in
/usr/$(target_noncanonical)/bin no longer is functional. Using it results in:

gcc: error trying to exec 'cc1': execvp: No such file or directory

Digging around, it turns out that the internal paths are screwed up:

$ /usr/sparc-sun-solaris2.10/bin/gcc -print-prog-name=cc1
cc1

$ /usr/sparc-sun-solaris2.10/bin/gcc -print-search-dirs
install: /usr/sparc-sun-solaris2.10/bin/../lib/gcc/sparc-sun-solaris2.10/4.4.3/
programs:
=/usr/sparc-sun-solaris2.10/bin/../libexec/gcc/sparc-sun-solaris2.10/4.4.3/:/usr/sparc-sun-solaris2.10/bin/../libexec/gcc/:/usr/sparc-sun-solaris2.10/bin/../lib/gcc/sparc-sun-solaris2.10/4.4.3/../../../../sparc-sun-solaris2.10/bin/sparc-sun-solaris2.10/4.4.3/:/usr/sparc-sun-solaris2.10/bin/../lib/gcc/sparc-sun-solaris2.10/4.4.3/../../../../sparc-sun-solaris2.10/bin/
libraries:
=/usr/sparc-sun-solaris2.10/bin/../lib/gcc/sparc-sun-solaris2.10/4.4.3/:/usr/sparc-sun-solaris2.10/bin/../lib/gcc/:/usr/sparc-sun-solaris2.10/bin/../lib/gcc/sparc-sun-solaris2.10/4.4.3/../../../../sparc-sun-solaris2.10/lib/sparc-sun-solaris2.10/4.4.3/:/usr/sparc-sun-solaris2.10/bin/../lib/gcc/sparc-sun-solaris2.10/4.4.3/../../../../sparc-sun-solaris2.10/lib/:/usr/sparc-sun-solaris2.10/sys-root/lib/sparc-sun-solaris2.10/4.4.3/:/usr/sparc-sun-solaris2.10/sys-root/lib/:/usr/sparc-sun-solaris2.10/sys-root/usr/lib/sparc-sun-solaris2.10/4.4.3/:/usr/sparc-sun-solaris2.10/sys-root/usr/lib/

(quick summary: the required path /usr/libexec/gcc/sparc-sun-solaris2.10/4.4.3/
is not in there)

The decorated compiler works just fine though:

$ /usr/bin/sparc-sun-solaris2.10-gcc -print-prog-name=cc1
/usr/libexec/gcc/sparc-sun-solaris2.10/4.4.3/cc1

Further digging seems to indicate that this was caused by r118765, where the
configured in paths only are added if the binary is in $(bindir).

I'm hoping this is only an oversight and someone forgot about this extra bindir
for cross-compilers as this regression is causing quite a bit of pain here.
