Problems with RTEMS installation - coming from 4.10

[Wendell Silva]

Hi Mr. Kucinskis,

Please, try this:

gcc  -mcpu=cypress -ffunction-sections -fdata-sections -Wall
-Wmissing-prototypes -Wimplicit-function-declaration -Wstrict-prototypes
-Wnested-externs -I${prefix}/sparc-rtems4.11/sis/lib/include
-B${prefix}/sparc-rtems4.11/sis/lib -specs bsp_specs -qrtems -lrtemsbsp
-lrtemscpu test.c -o test.exe

You can also use Makefile.{leaf|dir|lib} at RTEMS source
code/make/Templates as "inspiration".

Hope it helps you.

--Wendell.
