You are using the ELF file format right?  In the gABI a program header 
table is actually non-optional for executables and shared libs.  
Obviously a psABI can do mostly whatever it likes, but not having PHDRs is 
_very_ unusual.  They aren't specific to dynamic linking: after all, even 
static executables need to be loaded somewhere, by kernel or boot loader 
or ROM or $othermagic, and the program headers describe what and where to 
load.  So, you really might want to reconsider.  At least one PT_LOAD 
segment covering the whole file would be good.


Ciao,
Michael.
