Allow spaces in COB_CC
This (small) PR allows the COB_CC variable to contain spaces, by adding quotes to any sprintf that use it.
Otherwise, one would need to escape all the spaces in COB_CC, and while this is acceptable "in general", this is slightly inconvenient, and besides the other variables do not work this way (for instance try escaping spaces in COB_CONFIG_DIR and you'll see it fails finding the config files - if the path contains spaces).
This of course works as long as COB_CC only contains the path to the C compiler and no argument - which should be the case since arguments should go in COB_CFLAGS & friends.
This would also allow us to get rid of the gcobc wrapper we have in our Windows installer (cf. your comment: "I'd like to know what "gcobc" is"), whose sole purpose is to call cobc with a space-escaped COB_CC.
EDIT: probably needs more work, considering the failures on Windows (had only tested on Linux so far)
As you also see in the failing tests - that doesn't work this way as we copy over verbatim what is in the CC variable - and things like -std and -march are commonly set that way.
Note: the more common way is to not use full paths for the binaries but instead prefix its path to PATH.
Should we close this (and you prefix PATH with the directory in gcobc)?
Yup, let me close this.
