Fatal errors cross compile under Linux Gentoo (x64)

I use Linux Gentoo х86_64 (uname -a say: Linux gentoo-x64 3.10.25-gentoo #1 SMP Mon Jan 6 20:16:23 FET 2014 x86_64 Intel(R) Core(TM) i7-3770K CPU @ 3.50GHz GenuineIntel GNU/Linux)

Installed packages:

emerge portage-utils
emerge crossdev
crossdev -t i686-pc-mingw32
crossdev -t x86_64-pc-mingw32
emerge-wrapper --init
emerge nasm
ARCH="x86" i686-pc-mingw32-emerge nasm
ARCH="amd64" x86_64-pc-mingw32-emerge nasm

I have compiled zlib, openssl, icu, postgresql ... and then tried to compile Qt 5.2.0. the following command:

../qt-src-linux/configure -prefix /usr/local/Qt-5.2.0-x32 -opensource -confirm-license \
-plugin-sql-psql -I/root/qt/pgsql-x32/include -I/root/qt/icu-x32/include \
-L/root/qt/pgsql-x32/lib -L/root/qt/icu-x32/lib -opengl -no-eglfs -no-kms \
-no-compile-examples -icu -silent -xplatform win32-g++ \
-device-option CROSS_COMPILE=i686-pc-mingw32-

Result:

1) During the phase of "make install" the start of extra compilation 0_o
2) Completed incorrectly, note command "cp"

"cp -f \root\qt\qt-src\qtdeclarative\examples\quick\tutorials\gettingStartedQml\filedialog\qmldir ..\imports\FileDialog"

Windows-style slash!

Sorry for my English, I use a translator :-\
