[7u] diff fixes for export_debug_jdk in jdk/hotspot/make/Makefile

[Francis ANDRE]

Hi

The export_debug_jdk target from jdk7u/hotspot/make/Makefile never exports the

Z:\JDK\hsx\jdk7u\hotspot\build\windows\export-windows-i586\debug directories 
into

Z:\JDK\hsx\jdk7u\hotspot\build\windows\jdk-windows-i586

but it updates
Z:\JDK\\hsx\jdk7u\hotspot\build\windows\jdk-windows-i586\debug which is 
useless...
