RTEMS Build Problems on OpenBSD

[Adam Szeliga]

I have tried to compile rtems on a FreeBSD 4.1 and I have similar error.
I discover that somewhere in the source tree is used make not gmake.
Make can't export CC, ASM ...., but I received only warning.
Later during compilation I received error like Mike have.
To test this idea I simply make copy ordinary make to make.1 and link
make to gmake. After that everything was OK !
It is need to verify the source three where the simly make is used
insted gmake
