>Description:
devel/pcre fails to build on Solaris 10 after these messages:
/usr/pkg/bin/pdksh ./libtool --tag=CXX    --mode=link g++   -O -Wno-format

*** Error code 1

The root cause is in the using:
/usr/lib/crti.o
/usr/lib/values-Xa.o
/usr/sfw/lib/gcc/i386-pc-solaris2.10/3.4.3/crtbegin.o
/usr/sfw/lib/gcc/i386-pc-solaris2.10/3.4.3/crtend.o
/usr/lib/crtn.o
instead:
/usr/lib/amd64/crti.o
/usr/lib/amd64/values-Xa.o
/usr/sfw/lib/gcc/i386-pc-solaris2.10/3.4.3/amd64/crtbegin.o
/usr/sfw/lib/gcc/i386-pc-solaris2.10/3.4.3/amd64/crtend.o
/usr/lib/amd64/crtn.o

And the problem is simular to pkg/45102.

After manual patching of work/.wrapper/tmp/cache build was complete.
But I do not understand how this file is formed in order to provide a patch.
>How-To-Repeat:
On Solaris10/amd64:
# ./bootstrap --abi=64
(also I patched bootstrap to use x86_64 as MACHINE_ARCH)
# cd ../devel/pcre
# bmake
>Fix:
