[Development] QT 4.8 sysroot use

[Stephane Cerveau]

Dear all,

Is there a way to use the sysroot param in QT 4.8 as it is used in QT5.
Indeed when we install a cross compile with -prefix, the sysroot dir is 
not used in QT 4.8.

I would like to use PKG_CONFIG_SYSROOT_DIR to build apps ( such as 
webkit) but if I install QT 4.8 in a folder SYSROOT_DIR/usr, the .pc 
files contains prefix=QT_INSTALL_PATH instead of /usr.
Any help would be appreciate.
Best regards.

Stéphane
