RFR[P1]: 8055744 - 8u-dev nightly solaris builds failed on 08/20

[Jesper Wilhelmsson]

Hi,

On Solaris the HS_ALT_MAKE variable was not passed to vm.make when creating the 
mapfiles which lead to mapfile-ext not being found and later a linker error due 
to symbols declared in the extra mapfile not being found.

The hotspot makefiles are .. interesting .. yes.

The proposed solution is to include defs.make where HS_ALT_MAKE is set up into 
vm.make on Solaris.

This is a P1 so if you feel comfortable with the hotspot makefiles, please have 
a look.

Thanks!
