dev-cpp/tbb: fix underlinking on musl
Avoid *context APIs. In theory, may not be needed (shouldn't be) given we've fixed our packaging of libucontext, but let's do this anyway as the fix is upstream, and it avoids possible otehr issues.

+Subject: [PATCH] Make tbb compile with musl libc (#748)
+
+TBB resumable tasks are implemented using getcontext() and setcontext()
+on Unix-like systems. These functions are deprecated in the recent
+versions of POSIX and may not exist. musl libc does not provide these
+functions.
+
+There's unfortunately no way to detect musl (musl intentionally do not
+define macros like `__MUSL__`), so __TBB_RESUMABLE_TASKS is defined if
+`__GLIBC__`. glibc-compatible libc's such as uClibc defines `__GLIBC__`,
+so it should work as a catch-all condition.
