Comment 2 for bug 49192

The patching fix is as follows:

Append the following four lines:

/* Add these three lines to get us a PT_GNU_STACK header */
#ifdef __ELF__
.section .note.GNU-stack,"",%progbits
#endif

To all *.S source files. Use the below script:

e="/* Add these three lines to get us a PT_GNU_STACK header */
#ifdef __ELF__
.section .note.GNU-stack,\"\",%progbits
#endif"
for i in `find . -name \*.S`; do echo "$e" >> "$i"; done

Submit resulting changes upstream when finished and well tested, cite Ubuntu mainline as example.
