Thank you for the info. I have tried to compiled Qt with gcc

$  gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/opt/gnu/gcc-4.6.0/libexec/gcc/i386-pc-solaris2.11/4.
6.0/lto-wrapper
Target: i386-pc-solaris2.11
Configured with: ../gcc-4.6.0/configure --prefix=/opt/gnu/gcc-4.6.0 
--enable-shared --disable-libtool-lock
--target= --enable-objc-gc --disable-libada --enable-libssp 
--enable-languages=c,c++
--enable-threads=posix --enable-tls=yes --with-system-zlib 
--with-gnu-ld --with-ld=/usr/gnu/bin/ld

--with-mpfr-lib=/usr/lib
--enable-c99 --enable-nls --enable-wchar_t 
--enable-libstdcxx-allocator=mt --with-pic --enable-multilib
Thread model: posix
gcc version 4.6.0 (GCC)


and this time compilation completed with no problems. So it seems that 
GNU ld does something
magical...
