+When running patchelf on some existing patchelf'd binaries to change to longer
+RPATHS, ldd would report the binaries as invalid. The output of objdump -x on
+those libraryies should show the top of the .dynamic section is getting trashed,
+something like:
+
+0x600000001 0x0000000000429000
+0x335000 0x0000000000335000
+0xc740 0x000000000000c740
+0x1000 0x0000000000009098
+SONAME libglib-2.0.so.0
+
+(which should be RPATH and DT_NEEDED entries)
+
+This was tracked down to the code which injects the PT_LOAD section.
+
+The issue is that if the program headers were previously relocated to the end
+of the file which was how patchelf operated previously, the relocation code
+wouldn't work properly on a second run as it now assumes they're located after
+the elf header. This change forces them back to immediately follow the elf
+header which is where the code has made space for them.
