Can I use the GNU toolchain (gcc, etc) to build applications for the Blackfin processors?
Yes. More information can be found at: http://blackfin.uclinux.org/gf/project/toolchain
And can those applications be debugged with HPPCI-ICE or HPUSB-ICE in a windows environment?

No, they cannot. The Analog Devices Emulators are not supported by any open source software; they are only supported by the VisualDSP++ Environment. Additionally, the binaries produced by the GNU tools are of a different format to the format used by VisualDSP++, so uClinux applications cannot be debugged within the VisualDSP++ environment.
The uClinux site contains further information regarding supported JTAG debuggers for use with the GNU toolchain:
The gnICE(http://docs.blackfin.uclinux.org/doku.php?id=hw:jtag:gnice) is a good JTAG ICE to start with. The required software (gdb-proxy) works in Linux and Windows.
for archival purposes, the ADI ICE-100B works now with the GNU Toolchain in the 2010R1 and newer releases
