Revert "Fix gcc compile error: redundant redeclaration of ‘environ’ [-Werror=redundan...

Breaks the build on FreeBSD which doens't have an environ declaration.
The CMake check_symbol_exists call sets `HAVE_DECL_ENVIRON` to an empty
variable (which means if(DEFINED) suceeds). This normalization should not
be necessary as it will be handled correctly by `#cmakedefine01`. If not,
all the other HAVE_* defines would also be wrong.

This reverts commit e8b34b419e44e0b95622f45c0f17487e241b1961.
