Rewrite help texts for features enabled by default
As some features are enabled by default, configure --help should help the builder to disabled them. This PR changes configure --help output this way:
- --enable-wallet enable wallet (default is yes)
+ --disable-wallet disable wallet (enabled by default)
- --enable-tests compile tests (default is yes)
+ --disable-tests do not compile tests (default is to compile)
- --enable-hardening attempt to harden the resulting executables (default
- is yes)
+ --disable-hardening do not attempt to harden the resulting executables
+ (default is to harden)
- --enable-ccache use ccache for building (default is yes if ccache is
+ --disable-ccache do not use ccache for building (default is to use if
found)
The other three occurrences (--enable-static, --enable-shared and --enable-fast-install) are unfortunately upstream...
