Add Suffix option in 'Extensions Settings'

[murielgodoi]

Is your feature request related to a problem? Please describe.
Programmers are unable to add compilation parameters that should be placed at the end of the command, e.g., -lm.
"Compiler flags" come after gcc or g++, so it doesn't work for that purpose.

Describe the solution you'd like
Add an extra field in the 'Extensions Settings' labeled 'suffix' to allow the setting of that parameter.
