5ff3b5cafc build: Add pthreads to list of avutil extralibs

7cb1d9e2db build: Fine-grained link-time dependency settings 
Previously, all link-time dependencies were added for all libraries,
resulting in bogus link-time dependencies since not all dependencies
are shared across libraries. Also, in some cases like libavutil, not
all dependencies were taken into account, resulting in some cases of
underlinking.

To address all this mess a machinery is added for tracking which
dependency belongs to which library component and then leveraged
to determine correct dependencies for all individual libraries.

21cca00dfe build: Explicitly disable external libraries when not explicitly enabled 
Leaving those variables in an undefined state allows them getting implicitly
enabled when they are declared as weak dependencies of other components.
In that case, the library check is not run and required linker flags are not
added, resulting in a failing build.

Fixes linking when enabling libfreetype without libfontconfig.

7208e5b5d6 configure: Restructure the way check_pkg_config() operates 
Have check_pkg_config() enable variables and set cflags and extralibs
instead of relegating that task to require_pkg_config. This simplifies
require_pkg_config(), is consistent with what other helper functions
like check_lib() do and allows getting rid of some manual variable
setting in places where check_pkg_config() is used.

9127ac5ebc configure: Add name parameter to require_pkg_config() helper function

Place all temporary files within a single, quasi-atomically created
temporary directory rather than relying on unsafe 'mktemp -u'. This
prevents possible race conditions in case two parallel 'mktemp -u' calls
returned the same path. Additionally, it reduces TMPDIR pollution by
keeping all test files in a single subdirectory.

If we only have a target compiler but no host compiler, the $type
variable will be empty once.

(Currently we fail to do a cross build if no host compiler is available
due to using the host compiler for processing option lists though.
But despite that, this comparison in configure needs quotes.)

correctly, otherwise there are undefined references to functions for other
architectures and disabled components.

-O1 is the minimal optimization flag for MSVC that does include DCE.

f22da2cdf9 configure: add -fPIE instead of -pie to C flags for ThreadSanitizer 
-pie was added to C flags for ThreadSanitizer in commit
19f251a288. Under clang 3.8.0, the -pie
flag causes a compiler warning and a linker error when running configure
--toolchain=clang-tsan. Here is an excerpt from config.log:

clang ... -fsanitize=thread -pie -std=c11 -fomit-frame-pointer -pthread -c -o /tmp/ffconf.A8SsaoCF.o /tmp/ffconf.JdpujQlD.c
clang: warning: argument unused during compilation: '-pie'
clang -fsanitize=thread -pie -Wl,--as-needed -o /tmp/ffconf.2iYA4bsw /tmp/ffconf.A8SsaoCF.o -lm -lm -lbz2 -lz -pthread
/usr/bin/ld: /tmp/ffconf.A8SsaoCF.o: relocation R_X86_64_PC32 against undefined symbol `atan2f@@GLIBC_2.2.5' can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: final link failed: Bad value
clang: error: linker command failed with exit code 1 (use -v to see invocation)

To be conservative, I changed -pie to -fPIE. But the documentation seems
to imply just -fsanitize=thread is enough:
