[PATCHv1] Fix building error with '-O2' in sysroot path

Characters like '-O2' or '-Ofast' will be replaced by '-O1' and '-O0'
respectively when compiling cipher and random in the filesystem
paths as well if they happen to contain '-O2' or '-Ofast

If we are cross compiling libgcrypt and sysroot contains such
characters, we would
get compile errors because the sysroot path has been modified.

Fix this by adding blank spaces and tabs before the original matching
pattern in the sed command.

Feels like we should both backport that _and_ pass —disable-O-flag-munging, as we control the compiler flags.

Sorry for late reply.

It is difficult to control -O1 for cipher and -O0 for random at the same time in OE environment along with patch file.
so keeping same change as it is.
