0584a78d9b Fixed issue with previous changes in glibc PRNG 
With the previous changes the PRNG was faster but didn't work on all instances.

7acd739002 Finished integrating new glibc PRNG code and further optimizations 
On my laptop the difference with these new changes, compared to the older code is more than 4x faster. The code was tested on ~10 different data sets and seems to work fine.

7738fda7d8 Improvement in glibc PRNG cracking 
The code is based on a precomputed initial seed table, instead of re-seeding from scratch everytime the whole state. On my x86 test machine this new code seems to be ~60% faster.

Some further testing and tuning may be needed.

Credits to @1yura.

ce5d96b661 Added casts to correct types when printing elapsed time

65dd9975da Properly removed tomcrypt LTC_ARGCHK via config macro 
This way <signal.h> doesn't get included and (hopefully) the program compiles on macOS without _DARWIN_C_SOURCE.

1ddc765477 Revert "build tomcrypt sha256 code as separate object" 
This reverts commit e552d93a50a25e902dc6b44d29f174fd9a8671bb.

Usign GCC version 5.4.0 20160609 the code was 3 times slower (probably due to missing inlining and other optimizations). The binary was also >15kB bigger.

a07ebfb376 tomsfastmath: further size optimizations 
sources list created via

    make clean ; make CC=gcc LDFLAGS="-Wl,--gc-sections" CFLAGS="-O -ffunction-sections"
    readelf -a pixiewps | grep '\.c' | awk '{print "./" $8 " \\"}' > tfm_used.txt

and some manual cleanups.

2b229ba129 tomsfastmath: prefer size over speed 
we can disable highly optimized mul/sqr operations for about 30% speed
decrease but saving a lot in binary size.
only build the files necessary by including an explicit list of filenames
rather than doing a wildcard over tfm/*.c.

6985cff7b5 tomfastmath: fix compile with tinycc 
compiling with tinycc, we get:

7576a68717 Fixed UB due to int promotion before shifting of u8 values 
Added casts to u32 for 'rcons' and 'Td4s' which are of type uint8_t*, so their elements, before being shifted, are promoted to int (not to unsigned int) unless explicitly casted, due to integer promotion rules of the C language.

This caused the "left shift of * by 24 places cannot be represented in type 'int'" error when compiling with GCC's -fsanitize=undefined.

The code is from an old version of wpa_supplicant/hostapd.
