Subject: cmake: honor `CMAKE_C_FLAGS` in test 1119 and 1167
X-Git-Tag: curl-8_16_0~165
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a19bd4321030c6ea18e3bbec411dfd49961a1f71;p=thirdparty%2Fcurl.git

cmake: honor `CMAKE_C_FLAGS` in test 1119 and 1167

`CMAKE_C_FLAGS` is not set by curl, but may contain custom options
required for a successful compiler run, when invoked by these tests.

One such case is when configuring Visual Studio or clang-cl via compiler
options, instead of envs.

Cherry-picked from #18301
Closes #18307
