 gcc/configure does not attempt to detect whether ld is GNU ld unless you
 specify a path to ld using --with-ld.  It defaults to assuming that GNU ld
 is not in use, which causes the target macro files necessary for use with
 GNU ld to not be included.  The same applies for as.  The excluded files are
 gcc/config/sparc/sol2-gld.h, gcc/config/sparc/sol2-gld-bi.h for ld, and
 gcc/config/sparc/sol2-gas-bi.h for as.
 
 In this particular case, the omission of sol2-gld-bi results in link_arch
 not including an emulation name to pass ld; GNU ld requires this and
 defaults to elf32_sparc, while Solaris ld is capable of determining whether
 32- or 64-bit operation is desired based on the format of the supplied
 object files.
 
 As a workaround, configure with "--with-gnu-as --with-gnu-ld" to force the
 use of the GNU tools, or "--with-as=/usr/local/bin/as
 --with-ld=/usr/local/bin/ld" to force gcc/configure to detect whether as and
 ld are the GNU versions.  My preference is for the former.
 
 The fix would involve making gcc/configure set with_gas and with_gnu_ld
 appropriately based on the as and ld that will be used by the compiler
 before running gcc/config.gcc.  gcc/configure checks for which as and ld
 will be used a bit later in the process, so this would most likely involve a
 minor reordering.
