---------------------------------+--------------------
 When building an application using the make build support (as given by the
 example in make/Templates/Makefile.leaf), and when the used toolchain has
 a vendor identifier as part of the target triplet (for example
 sparc-**gaisler**-rtems5), the build fails with the following kind of
 error:

 {{{
 <user_path>/make/custom/default.cfg:14: <user_path>/sparc-
 rtems5/leon3/make/bsp.cfg: No such file or directory
 make: *** No rule to make target '<user_path>/sparc-
 rtems5/leon3/make/bsp.cfg'.  Stop.
 }}}

 This seems to be due to `make/custom/default.cfg` which uses:
 {{{
 !#make
 (...)
 RTEMS_TARGET = $(RTEMS_CPU)-rtems$(RTEMS_API)

 include $(RTEMS_ROOT)/$(RTEMS_TARGET)/$(RTEMS_BSP)/make/target.cfg
 include $(RTEMS_SHARE)/make/host.cfg

 include $(RTEMS_ROOT)/make/main.cfg
 include $(RTEMS_ROOT)/$(RTEMS_TARGET)/$(RTEMS_BSP)/make/bsp.cfg
 }}}
 where `RTEMS_CPU` does not include the vendor id, and hence gives an
 incorrect target triplet in `RTEMS_TARGET`.

 This seems to be a regression between rtems 4.11 and rtems 5 introduced in
