m4: add Werror when checking for compiler flags
...
Seemingly that at some point clang started accepting _any_ flags,
whereas previously it would error out.
These days, you can give it -Whamsandwich and it will succeed, while
at the same time throwing an annoying warning.
Add -Werror so that everything gets flagged and set accordingly.

m4.include/mc-cflags.m4: report real compiler in MC_CHECK_ONE_CFLAG instead of 'gcc'
...
Example use: CC=clang ./configure
Before the patch configure reported 'gcc' is being used:
checking whether gcc accepts -Wcomment... yes
checking whether gcc accepts -Wdeclaration-after-statement... yes
checking whether gcc accepts -Wfloat-equal... yes
checking whether gcc accepts -Wformat... yes
(config.log used proper ${CC})
After the patch it lies a bit less:
checking whether clang accepts -Wcomment... yes
checking whether clang accepts -Wdeclaration-after-statement... yes
checking whether clang accepts -Wfloat-equal... yes
checking whether clang accepts -Wformat... yes
