Public bug reported:

The GNU assembler segfaults with an invalid -march= option
Contact Information = n/a 
---uname output---
Machine Type = n/a 
A debugger is not configured
---Steps to Reproduce---
 $ as -march=foo
Segmentation fault
Userspace tool common name: as 
The userspace tool has the following bit modes: 64 

Userspace rpm: binutils-2.26.1-1ubuntu1~16.04.6

Userspace tool obtained from project website:  na 
*Additional Instructions for n/a:
-Attach ltrace and strace of userspace application.

The problem is not critical since usually 'as' is invoked through the gcc 
driver which itself errors out for wrong -march= options. It will only be a 
problem if somebody builds a more recent GCC from source and uses an -march= 
option for a machine not supported by the default binutils.

Please consider integrating the attached patch into 16.04 binutils.

The problem has been fixed in later binutils already. Ubuntu 18.04 does
not appear to be affected.

--> Package has to set corectly by Canonical
