If Wind River supplies GNU tools hosted on Sparc Solaris and targeted for
the m68k/VxWorks environment you use, then one option that you have would
be to get the source for those tools and rehost them on x86 Solaris yourself
(Wind River is obliged under terms of the GPL to make the sources available
if they distribute the GNU tools at all).  One would expect that all required
target-specific patches should already be present in any source you get from
Wind River to build a working Sparc-hosted version;  if that is true, I would
expect that rehosting on x86 Solaris should go quite smoothly if you follow
the instructions carefully.  At least, that has been my experience in the past.
For example, I was able (with no prior experience) to build binutils-2.6 and
gcc-2.7.2 from the sources on the February 1996 GNU CDROM in about two days
for a MIPS target hosted on Solaris2.4_x86.  It took somewhat longer to get
gdb-4.16 up because I had to write my own target-resident gdb stub, but
in your case the analogous component should be available from Wind River.
