Any GNU cross toolchain you install will provide a "plain-names"
version of the toolchain, and a "cross-names" version.  With
uClibc, I create these in seperate directories to make it easy
for people to pick whichever one they want to use.

    $(PREFIX)$(DEVEL_PREFIX)/bin/
                                 gcc
				 ld
				 etc...

    $(PREFIX)$(SYSTEM_DEVEL_PREFIX)/bin/
                                        v850-uclibc-gcc
					v850-uclibc-ld
					etc...

Normally, SYSTEM_DEVEL_PREFIX=$(DEVEL_PREFIX)/usr/bin so you
will (assuming DEVEL_PREFIX=/usr/v850-linux-uclibc) end up with:

    $ ls /usr/v850-linux-uclibc/bin/
    addr2line@  as@  cpp@   gcc@  ldd*  objcopy@  ranlib@   size@     strip@
    ar@         cc@  gasp@  ld@   nm@   objdump@  readelf*  strings@

    $ ls /usr/v850-linux-uclibc/usr/bin/
    v850-uclibc-addr2line@  v850-uclibc-cpp@   v850-uclibc-ldd@      v850-uclibc-ranlib@   v850-uclibc-strip@
    v850-uclibc-ar@         v850-uclibc-gasp@  v850-uclibc-nm@       v850-uclibc-readelf@
    v850-uclibc-as@         v850-uclibc-gcc*   v850-uclibc-objcopy@  v850-uclibc-size@
    v850-uclibc-cc@         v850-uclibc-ld*    v850-uclibc-objdump@  v850-uclibc-strings@

so they don't interfere with each other.  Have you set 
DEVEL_PREFIX = SYSTEM_DEVEL_PREFIX?
