Right.

info->shared is set either when DLL is to be created (-shared flag) or when relocatable 
executable should be created (-pie flag). Without this patch the -pie flag would make the 
linker think that we want to build a DLL (because it doesn't respect link_info.pie at 
all), but actually we want only relocatable EXE. The only difference between DLL and 
relocatable EXE is the DLL flag in PE header and the default base address. My patch just 
makes the linker correctly interpret these two differences between -pie and -shared.
