Those are compiler flags for the Sun compiler. Not a lot of help with gcc.

Sage now builds on OpenSolaris 32-bit, and passes all the Sage test suite.

That looks to be true.
But Solaris 10 has not died, neither or x86 or SPARC. The issues are seen on
Solaris 10 SPARC too, so it not just an x86 problem. Maxima is not complaining
on SPARC, but the elfdump command clearly shows the problem is in the ECL
library file. That problem exits on 64-bit SPARC too.

Two of the parts of Sage that are showing problems on 64-bit
Solaris/OpenSolaris
buids (ECL and Cliquer) give an output from that command above. So if the
link-editor thinks a file contains non-pic code, then it will present a problem.
The problem can't be Maxima, as I don't need to even build Maxima to show the
ECL code has this problem.
The MPIR library does not exhibit this issue.

Neither do most others. The only offenders in Sage are ECL, PolyBoRi and
Cliquer.
Sorry, the title is a bit confusing. The problem is seen
* 64-bit SPARC
* 64-bit Solaris 10 on x86
* 64-bit OpenSolaris on x86
Note also, I built your latest sources outside of Sage. The issue is seen there.
Note also, that there's this compiler warnings when I build on Solaris (or any
sort)

warning: too many arguments for format
When I use the debugging technique mentioned at
http://blogs.sun.com/rie/entry/my_relocations_don_t_fit
$ export LD_OPTIONS=-Dreloc
$ make
and look at the resulting output, it indicates to me, the problem is with dpp.c
- which maybe coincidence, or maybe not, is the same file giving a compiler
warning.
