Yang Tse b908376bef build: explain current role of LIBS in our Makefile.am files 
BLANK_AT_MAKETIME may be used in our Makefile.am files to blank
LIBS variable used in generated makefile at makefile processing
time. Doing this functionally prevents LIBS from being used for
all link targets in given makefile.

# to be such a case! See README.curl_off_t for further details.

# (current version is C:R:A)

# 1. if there are only source changes, use C:R+1:A

# 3. if interfaces were removed, then use C+1:0:0
