Fix calling convention incompatibility with vendor compiler
For the 20th anniversary of https://gcc.gnu.org/gcc-3.4/sparc-abi.html,
a new calling convention incompatibility with the vendor compiler (and
the ABI) has been discovered in 64-bit mode, affecting small structures
containing arrays of floating-point components. The decision has been
made to fix it on Solaris only at this point.
