ci: shippable: set build directory identically for all platforms

Further improve the ccache hit rate by setting the build directory
to be the same for all platforms. Prior to this, only the build for
the same platform could share cached files, because the file path is
part of the hash.

ci: shippable: enable ccache's 'unify' option

There is currently no caching possible between the various _make lines in
.shippable.yml, because they select different configuration flags. Since
all the files include $(out-dir)/include/generated/conf.h automatically,
the preprocessor output is therefore different simply due to the fact that
conf.h is different from one line to the other.

This is quite unfortunate, because most source files depend on a handful
of configuration flags only and therefore activating unrelated flags
should not cause a cache miss.

Addressing this problem is exactly the purpose of the 'unify' option of
ccache [1]. Activate it by setting CCACHE_UNIFY=true and CFG_DEBUG_INFO=n
before building. The lines that set DEBUG=0 or DEBUG=1 are adjusted to
produce the same result as before.

core: introduce configuration flags for debug info and optimization

Introduces CFG_CC_OPTIMIZE_FOR_SIZE (default y) which selects the C
compiler flag -Os and -O0 otherwise, and CFG_DEBUG_INFO (default y)
which selects the C compiler flag -g3 and assembler flag -g.

DEBUG=1 is kept for compatibility.

Being able to compile without -g is useful to get much better performance
from ccache thanks to its 'unify' option [1].

The legacy (GCC 4.9) toolchain has been deprecated in build.git [1]. As a

Travis CI build:

Fix the issue by downloading the toolchain manually and setting
AARCH32_CROSS_COMPILE. buildroot still needs COMPILE_LEGACY=y
to use the proper configuration file [2], and common.mk still needs
LEGACY_AARCH32_CROSS_COMPILE when COMPILE_LEGACY=y so set it too.
