gcc build error: Trouble closing elf file - gcc

Question

I’m compiling GCC on Solaris x86 and got the following error:
Assembler: optimize.c
"/var/tmp//ccMndPR3.s", line 85111 : Trouble closing elf file
gmake[3]: *** [cp/optimize.o] Error 1
I downloaded MPC, GMP and MPFR and extracted them into GCC source directory as mpc,gmp and mpfr directories and configure GCC source with:
$ ../gcc-5.2.0.src/configure --prefix=$HOME/gcc-5.2.0 --enable-languages=c,c++
I used gmake for executing the compilation tasks.
$ gmake
The file mentioned in the error message doesn’t exist.
$ ls -l "/var/tmp//ccEtAJ5n.s"
/var/tmp//ccEtAJ5n.s: No such file or directory
$ ls -l "/var/tmp/ccEtAJ5n.s"
/var/tmp/ccEtAJ5n.s: No such file or directory
I’m not sure how this can happen.
The file system has plenty of room:
$ df -h /var/tmp
Filesystem size used avail capacity Mounted on
/dev/dsk/c0t0d0s6 99G 27G 71G 28% /var
$ uname -a
SunOS sbdsvrwm566 5.10 Generic_150401-20 i86pc i386 i86pc
the only error message in config.log is as follows:
configure:5091: g++ -o conftest -g -O2 -static-libstdc++ -static-libgcc conftest.cpp >&5
g++: unrecognized option `-static-libstdc++'
conftest.cpp:11:2: #error -static-libstdc++ not implemented
configure:5091: $? = 1
configure: failed program was:
| /* confdefs.h */
| #define PACKAGE_NAME ""
| #define PACKAGE_TARNAME ""
| #define PACKAGE_VERSION ""
| #define PACKAGE_STRING ""
| #define PACKAGE_BUGREPORT ""
| #define PACKAGE_URL ""
| /* end confdefs.h. */
|
| #if (__GNUC__ < 4) || (__GNUC__ == 4 && __GNUC_MINOR__ < 5)
| #error -static-libstdc++ not implemented
| #endif
| int main() {}
the error apparently is due to the missing space between -static and -libstdc++. however, what is strange is none of the mentioned confdefs.h conftest.cpp exist either under the source or build directory or installed packages.
obviously the older gcc was used to compile the new gcc:
configure:4074: checking for gcc
configure:4090: found /usr/sfw/bin/gcc
configure:4101: result: gcc
configure:4330: checking for C compiler version
configure:4339: gcc --version >&5
gcc (GCC) 3.4.3 (csl-sol210-3_4-branch+sol_rpath)
