Yes, I am confident - it is part of the core run-time environment:
# lslpp -w | grep libc.a
/usr/ccs/lib/libc.a bos.rte.libc File
/usr/lib/libc.a bos.rte.libc Symlink
/usr/lib/threads/libc.a bos.rte.libc Symlink
And, bos.rte.libc cannot be uninstalled:
SELECTED FILESETS: The following is a list of filesets that you asked to
remove. They cannot be removed until all of their dependent filesets
are also removed. See subsequent lists for details of dependents.
bos.rte.libc 5.3.7.0 # Base Level Fileset
NON-DEINSTALLABLE DEPENDENTS: The following filesets depend upon one or
more of the selected filesets listed above. These dependents should
be removed before the selected filesets. Deinstallability checks
indicate
that these dependents should not be removed from the system;
therefore, the
selected filesets cannot be removed.

I gave up counting the number of dependents that "officially" are
dependents on bos.rte.libc after the count went above 200 - on a vanilla
system install.
I'll make a different test (skip if not aix) that find_library("c") must
succeed. The load has already been tested - with libc_name already
hard-coded.
