Minis support, rest

[Bruno Haible]

Here are the remaining problems, from a testdir of only the `./posix-modules`.
I'm not handling them now (since you are saying that the entire Minix libc is
in flux), but you should be aware of them:

========================= <math.h> =========================

- 'long double' and 'double' are the same types. Will that stay the same?
  If so, the modules
    floorl, ceill, truncl, roundl,
    sqrtl,
    cosl, expl, logl, sinl, tanl, acosl, asinl, atanl,
    frexpl, printf-frexpl, ldexpl, isnanl
  can be simplified to use the 'double' argument function.

- Missing cbrt() function:
gltests/test-cbrt.c:36: undefined reference to `_cbrt'

- Missing copysign() function:
test-copysign.c:24: error: 'copysign' undeclared here (not in a function)

- Missing erf() function:
gltests/test-erf.c:36: undefined reference to `_erf'

- Missing erfc() function:
gltests/test-erfc.c:36: undefined reference to `_erfc'

- Missing isinf() macro:
test-isinf.c:26:3: error: #error missing declaration

- Missing j0() function:
gltests/test-j0.c:36: undefined reference to `_j0'

- Missing j1() function:
gltests/test-j1.c:36: undefined reference to `_j1'

- Missing jn() function:
gltests/test-jn.c:36: undefined reference to `_jn'

- Missing lgamma() function:
gltests/test-lgamma.c:36: undefined reference to `_lgamma'

- Missing log1p() function:
gltests/test-log1p.c:36: undefined reference to `_log1p'

- Missing logb() function:
gltests/test-logb.c:38: undefined reference to `_logb'

- Missing nextafter() function:
gltests/test-nextafter.c:37: undefined reference to `_nextafter'

- Missing y0() function:
gltests/test-y0.c:36: undefined reference to `_y0'

- Missing y1() function:
gltests/test-y1.c:36: undefined reference to `_y1'

- Missing yn() function:
gltests/test-yn.c:36: undefined reference to `_yn'
