Daniel Kolesa f3e0033a06 meson: remove the subproject-based library checking 
this is not idiomatic, and should not be done (and it did not even
work in the first place); meson is capable of building both
libraries via library() and then you can choose on commandline

it defaults to only shared, but we want both out of box, so specify
that

Daniel Kolesa 6026980cac ppc, ppc64: tag global symbols as functions 
it is necessary to tag these symbols as functions otherwise the
linker gets confused; this previously manifested as the internal
functions (pre-rename) like __getcontext leaking into the symbol
table of things linked against libucontext that used the ucontext
POSIX API through the weak aliases

it also had another bad effect and that is if you tried to use
libucontext's API (post-rename), the linker would warn you during
compile time that the type is unknown, and the resulting program
would crash at runtime

after properly tagging everything, I no longer notice any leakage,
i.e. there don't seem to be any references to the aliased symbols
in the resulting symbol table when using the aliases, and using
the libucontext prefixed symbols directly also works

Daniel Kolesa 03927d4c4c build: depend on headers for the static target 
this fixes static-only build, i.e. "make libucontext.a"
